LETTER FROM THE DIRECTOR

The ABC-UTC consortium of universities works in partnership with a host of stakeholders to provide the best possible service to the profession and public. A distinct feature of the ABC-UTC is its close collaboration with AASHTO COBS members, FHWA, and the members of the bridge profession. The ABC-UTC projects are selected through collaborative discussions among all stakeholders to best suit a need for ﬁlling the knowledge gap in the area of ABC. The program has already developed some

practical products including prefabricated bridge railing, ABC database, folded steel plate girder modular system with lengths exceeding 100 ft., UHPC based solutions for retrofitting bridge elements, and UHPC shells as formworks. The ABC-UTC continues this endeavor by developing new products and solutions, including short courses on various ABC topics, and through the development of non-proprietary UHPC mix to provide the resources highly demanded among the bridge professionals. Bridge consultants have joined the consortium to participate in ABC-UTC activities, such as mentoring, to efforts assist in the development of a more knowledgeable workforce capable of implementing new frontiers in ABC. Starting with the new 2016 ABC-UTC grant, the process of proposing and selecting projects has been streamlined according to the ABC-UTC Operations Manual, which was developed specifically for this program based on input from stakeholders. Following the lead of the extremely successful 2014, 2015, and 2017 National ABC Conferences, the ABC-UTC is now organizing the 2019 International ABC Conference focusing on innovation, automation, and resilience. More than 700 bridge professionals attended each of the previous conferences. The ABC-UTC has continued its free online monthly webinars, which, on average, are viewed by more than 5,000 bridge professionals. Almost all state department of transportation officials listen to these webinars, in addition to consultants and other bridge professionals. Quarterly research seminars and in-depth webinars are additional educational activities undertaken by ABC-UTC. Additionally,

twice a year, ABC-UTC holds a Research Day in which principal investigators of all active projects present new developments, their progress, and challenges. The last Research Day included presentations for 27 active projects. Almost all ABC-UTC projects are collaborative with partner universities working jointly on a given project. The ABC-UTC now provides access to a platform for new and innovative bridge engineering solutions for bridge owners and the bridge community through the ABC-UTC website under Implemented Advanced Technologies (https://abc-utc.ﬁu.edu/resources/implemented-advancedtechnologies/)proven to advance technologies. The ABC-UTC program provides an excellent platform for graduate and undergraduate students by exposing them to research projects that address real-world and contemporary problems. Through initiatives such as the ABC-UTC mentoring program, students receive professional and educational advice and are able to expand their professional networks. ABC-UTC partner universities conduct a variety of educational and workforce development activities, among them the highly popular Summer Camps, which attract many underrepresented and minority K-12 students. The camps provide students, parents, and teachers with opportunities to learn about, and develop an interest in bridge engineering. The ABC-UTC welcomes your thoughts and suggestions on how it might better support the bridge profession in the effective implementation of ABC across the United States and beyond.

LEADERSHIP

The Accelerated Bridge Construction University Transportation Center (ABC-UTC) was established as a Tier 1 UTC with a grant from the U.S. Department of Transportation (USDOT) in 2013. Dedicated to research, education and workforce development, and technology transfer in the area of ABC, the program has attained great achievements since its inception and has become the hub for promoting ABC and disseminating new and innovative means for the construction repair, and rehabilitation of bridges. ABC-UTC, by end of its 2013 grant had become the hub for promoting ABC and disseminating new and innovative means for the construction, repair, and rehabilitation of bridges. In 2016, ABC-UTC received a new five-year grant from the USDOT to continue its critical mission of providing means and methods for building a resilient transportation system through research and innovation. From the beginning, a strong emphasis of this program has been on developing engineering solutions that deliver practical, proven impacts on the construction industry and exert significant influence on design and construction specifications. The result has included a series of tangible products from research projects that are either already in use or on the way to shaping how new generations of bridges are to be made. ABC-UTC has greatly facilitated the development and dissemination of a wealth of information in the area and has allowed consortium members to serve the bridge community in a superb manner both locally and nationally. FIU and its partners, with crucial help from major stakeholders in the transportation field, have effectively identified the knowledge gap required for promoting ABC methods, and have undertaken multiple research projects not only to address the gap but also to work toward resolving anticipated future problems. Some of these projects are described in this highlight report. For a more detailed description of the research projects, please visit the ABCUTC web site (www.abc-utc.fiu.edu). With the initiation of the 2016 grant, the selection of research projects has been streamlined and ABC-UTC processes have been facilitated through the development and updating of an operations manual that in turn has added to the

efficiency of the center operation. The Operation Manual provides transparent and defined steps governing the research, education and workforce development, and technology transfer activities of ABC-UTC. Furthermore, the newly instituted Technology Transfer Plan has provided a much-needed platform for registering the research output, outcome, and impact, as well as a set of concise and essential metrics for evaluation of the performance of the program. The ABC-UTC center at FIU is proud to have fulfilled and surpassed the requirements set forth with this plan. Innovation and revolutionary ideas are at the forefront of ABC-UTC program goals. We realize that the success and utility of the program depend strongly on new ideas and products. ABC-UTC is also looking to the future by undertaking initiatives that have the potential to shape the future of bridge engineering. Advances in technologies such as robotics and 3D printing, solutions that were thought impossible a few years ago, are becoming increasingly more feasible as ABC-UTC is undertaking initiatives to facilitate the introduction of new ideas into bridge engineering. ABC-UTC has embarked on a mission to make the knowledge and experience of ABC available to bridge owners and the entire industry. As part of this endeavor, a non-proprietary UltraHigh-Performance Concrete (UHPC) is being developed and verified by the partner universities in order to facilitate the use of this material in ABC with the goal of reducing the unit cost of the material. ABC-UTC continues not only to lead the research and development of new sets of knowledge in the area of ABC, but also to disseminate the information and educate the profession and stakeholders. ABC-UTC contributes significantly to the development of the next generation of workforce who will be fully equipped with state-of-the-art knowledge and capable of implementing ABC. In addition, an educated workforce will effectively transfer the experience to the end users. The program has proven to be greatly influential and successful in aligning the bridge industry with improvement in cost, utility, and public safety for bridge structures.

Floyd The primary objective of the project is to develop guidance for an “ABCUTC Non-Proprietary UHPC Mix” design produced with local materials that can achieve the necessary mechanical properties and durability for use in bridge component connections. The ﬁve ABC-UTC partner institutions will coordinate efforts to examine material properties, reinforcing bar development length, shear behavior, full-scale joint behavior, and durability of the “ABC-UTC Non-Proprietary UHPC Mix.”

PERFORMANCE EVALUATION OF STRUCTURAL SYSTEMS FOR HIGH SPEED RAIL IN SEISMIC REGIONS PI: John Stanton The overall goals of the proposed research are to evaluate the structural systems presently under consideration by CAHSR, develop alternative concepts and obtain feedback from CAHSR to guide their further development, and develop preliminary calculations and drawings for selected Conceptual Designs for CASHR evaluation.

NEW SEISMIC-RESISTING CONNECTIONS OR CONCRETE-FILLED TUBE COMPONENTS IN HIGHSPEED RAIL SYSTEMS

DESIGN OF CFST COMPONENTS AND CONNECTIONS FOR TRANSPORTATION STRUCTURES: COURSE MODULE

PI: Dawn Lehman and Charles Roeder The overall goals of the proposed research are to investigate CFT and other column-to-pile connections through a literature review, select column-topile connections for study in consultation with the CAHSR technical team, investigate the seismic response and resilience of selected connections through FE analysis, and conduct limited structural analysis simulation and parametric study for a HSR bridge system.

PI: Dawn Lehman The objective is to develop a multi-part course module appropriate for practicing bridge engineers and graduate students. In addition, it is expected that parts of the course will be relevant to other transportation systems including ports and high-speed rail.

PI: Paolo M. Calvi While considerable information has been developed about many characteristics of UHPC, information about shear behavior is sparse. This project investigates experimentally the behavior of UHPC mixes subject to a variety of stress states, focusing on shear and including variables such as mix design and ﬁber content. The experimental data collected in this project will be used to develop a constitutive model for the shear behavior in UHPC, and in particular the non-proprietary UHPC materials being developed by the partner universities.

DEVELOPMENT OF ABC COURSE MODULE – SEISMIC CONNECTIONS PI: John Stanton The goal of the proposed research is to provide a summary of the different types of seismic connection that can be achieved using ABC methods, for the beneﬁt of future users who may not be familiar with the extensive literature on the subject. Many different connection types have been developed, so the primary effort will go into the process of categorizing them in a rational way.

PI: John Stanton The overall goal of the proposed research is to investigate the long-term performance of projects that were constructed in the past using ABC methods, and therefore to determine whether the short-term beneﬁts of ABC are matched by good long-term performance as well. This will be done by selecting two ABC bridges in Washington State and using them as indicators of others. Washington State was one of the ﬁrst to adopt the use of precast, prestressed concrete girders, and so offers the opportunity to review a long history of that type of construction.

TSUNAMI DESIGN FORCES FOR ABC RETROFIT PI: Marc Eberhard The catastrophic damage that tsunamis cause to coastal communities is often exacerbated by the destruction of much of the transportation infrastructure. To reduce the impacts of tsunamis, it is essential that transportation agencies retroﬁt bridges using methods that minimize disruption to the current transportation system. This project leverages funds from the University of Washington to provide initial estimates of forces that a tsunami would impose on a bridge as the result of debris-laden ﬂows.

RESEARCH PROJECT SPOTLIGHT

PI: Seung Jae Lee Graduate Research Assistant: Ali Bakhtiari

“This work paves the way for practical use of detailed computational simulations in demolition planning, which has great potential in reducing accident risks and construction delays. The project leverages an existing simulation and visualization platform (Blender) and provides and add-on that is specifically developed for bridge demolition simulations.” Anoosh Shamsabadi, Supervising Engineering Manager, California High-Speed Rail

OBJECTIVE:

Develop a numerical simulation technique that can realistically model, simulate and visualize the bridge demolition to underpin transparency in the communication process between structural engineers, contractors and stakeholders, which will better support the decision making.

SYNOPSIS:

Bridges represent a significant subpopulation of our civil infrastructure. A majority of these bridges are deteriorating fast and are in need of replacement or rehabilitation. The first step of those replacement/rehabilitation projects are typically to either entirely or partly demolish the existing structure. Therefore, proactive planning for controlled demolition is of utmost importance to proceed with the rest of construction project in a timely manner. Maintaining the integrity of neighboring infrastructure, e.g., permanent roadways, nearby transmission lines, and the safety of workers are critical issues, for which contingency plans also must be developed based on any feasible emergency scenarios. It is typically difficult to develop a general guideline/specification that can facilitate safe and efficient demolition, and very limited information has been available to guide structural engineers and contractors on how to proceed with the demolition of an existing structure. This lack of generalized procedure has led to structural engineers and contractors approaching the demolition work differently, and as a result, most states neither specify parameters for demolition equipment nor require the submission of contractor qualifications with the demolition plans. The potential hazards and inefficiency may be better controlled and possibly eliminated by leveraging computer simulation that can help realistically predict the demolition process. However, such computer tools for simulation-aided demolition are not available in the bridge engineering community. This study aims to enhance the predictive capabilities by exploring a set of numerical simulation techniques that can realistically model, simulate and visualize the bridge demolition, which will better support the engineers and contractors’ decision making.

CORROSION DURABILITY OF REINFORCED CONCRETE UTILIZING UHPC FOR ABC APPLICATIONS PI: Kingsley Lau, Atorod Azizinamini, David Garber Graduate Research Assistant: Mahsa Farzad

“The findings of this research are highly valuable to bridge owners considering Accelerated Bridge Construction and the use of Ultra High Performance Concrete as a repair material for reinforced concrete bridges in a marine environment.”

ABC-UTC 2017-2018 HIGHLIGHTS

Nancy Daubenberger, P.E., Assistant Commissioner, Minnesota Department of Transportation

OBJECTIVE:

To investigate the corrosion durability performance of UHPC joints between precast reinforced concrete sections.

SYNOPSIS: In the United States, ~30% of the ~600,000 highway bridges are labeled structurally deficient or functionally obsolete. Approximately 65% of the bridges in the United State are reinforced concrete, of which 40% are classified as structurally deficient or functionally obsolete. Many of these bridges are damaged due to chloride induced corrosion of the reinforcing steel. Structural members damaged by corrosion are typically repaired by removal of delaminated concrete and application of repair patches or jackets, but traditional repair methods have limitations due to the presence of incipient anodes after removal of the damaged concrete and replacement with chloride-free repair material. The development and application of effective repair methods and durable materials aiming at extending the lifetime of both existing and new structures is a critical issue. The enhanced mechanical and low permeability characteristics of ultra-high-performance concrete (UHPC) have been widely reported and make UHPC a material of interest for structural applications including rehabilitation of concrete structures. Application of UHPC can potentially result in both technical and economic advantages, including decreased reinforcement corrosion activity and an increase in service life. Because it is becoming more common to apply UHPC for rehabilitation to improve strength, improved protection against corrosion would serve as a complimentary benefit of this treatment. Experimental research on the corrosion durability of a proposed Accelerated Bridge Construction (ABC) solution to repair reinforced concrete elements in marine environments utilizing UHPC is presented in this report.

DELIVERABLE:

To establish guidelines for the corrosion durability performance of UHPC joints between precast reinforced concrete sections.

EXTENDING MAXIMUM LENGTH OF THE FOLDED STEEL PLATE GIRDER BRIDGE SYSTEM (FSPGBS), EXCEEDING 100 FT. WITH CAPABILITY TO INCORPORATE CAMBER PI: Atorod Azizinamini

“Vermont has hundreds bridges between 60 and 100 feet with many approaching the need for replacement or major rehabilitation. These are our bread and butter bridges and we always seek an ABC solution first. Vermont is pleased to see research and advancements in extending the length of the Folded Steel Plate Girder Bridge System up to 100’. With no need for internal or external cross frames for local or global stability, the Folded Steel Plate Girder Bridge System is sure to be in Vermont’s ABC tool box.” Kristin M. Higgins, P.E. , Structures Program Manager, Vermont Agency of Transportation

OBJECTIVE:

The main objective of this research is to develop a new version of FSPGBS with maximum span length, exceeding 100 ft. with allowance to incorporate camber.

SYNOPSIS:

The nation’s bridge inventory is aging, and most of substandard bridge spans needing replacement are under 100 feet in length. Concrete is currently the only economical material for these shorter girders. With available funding far less than bridge upgrade needs, a competitive alternative material is needed for accelerated replacement of a large number of substandard spans that are 100 feet and shorter in length. The existing Folded Steel Plate Girder Bridge System (FSPGBS), developed by researchers provides an economical short-span steel bridge alternative for spans less than 60 feet in length. This trapezoidal-shaped beam is lightweight and well suited for ABC applications. Its cross-section is stable without internal or external cross frames for streamlined fabrication and is open along the bottom for ease of safety inspection. Construction contractors and design consultants have recommended the development of a modiﬁed version of the FSPGBS for span lengths approaching 100 feet to provide a steel girder alternative to concrete girder bridges in this span range. Under this project, the maximum length of the FSPGBS will be extended to about 100 feet. Final report is published. Project outputs include design and fabrication details for a next-generation FSPGBS with a strengthened cross-section to accommodate spans up to 100 feet in length.

NDT METHODS APPLICABLE TO HEALTH MONITORING OF ABC CLOSURE JOINTS PI: Armin Mehrabi Graduate Research Assistant: Saman Farhangdoust Undergraduate Student: Sayed Feras Almosawi

“Bridge owners are concerned about the durability and the longevity of structures built using ABC and are seeking assurances about long term performance. Guidelines for the use of NDT methods to evaluate closure joints, a critical element of ABC, will give bridge owners the confidence they need.”

ABC-UTC 2017-2018 HIGHLIGHTS

Ahmad Abu-Hawash, Chief Structural Engineer, Iowa DOT

OBJECTIVE:

Review and identiﬁcation of practical and economical methods for ﬁeld inspection and damage detection of ABC closure joints, immediately after completion and periodically thereafter during its service life.

SYNOPSIS:

In Accelerated Bridge Construction (ABC), prefabricated bridge deck elements are connected using “Closure Joints.” Because of cast-in-place nature of closure joints that are expected to go into service and ﬁeld observations, there have been some concerns about their long-term durability. This has necessitated the need for health monitoring of ABC closure joints using Non-Destructive Testing (NDT) methods. Closure joints contain unique features and require special treatment when it comes to selecting the appropriate NDT technique. However, a clear guideline for selection of the most applicable NDT method for various types of closure joints have not been developed yet. To address this, a research project was carried out at ABC-UTC at FIU that included review of all relevant NDT methods and efforts for categorizing closure joints based on features affecting the use of NDT. Since the applicability of NDT methods depends heavily on the type of expected anomaly to be detected and its root causes, all potential defects and damages were identiﬁed and investigated using a Damage Sequence Tree (DST). Consequently, damage etiology for closure joints was established based on Fault Tree Analysis (FTA). Finally, a quantitative statistical analysis was performed to substantiate the selection of the most applicable NDT methods. The guideline and procedure developed can be readily used by bridge owners and consultants as a practical guideline for selection of NDT methods for health monitoring of ABC bridges with closure joints.

DELIVERABLE:

A guideline for selection of NDT methods for health monitoring of ABC Closure Joints. NDT Methods Suitable for each type of Defect in order of Priority

PERFORMANCE COMPARISON OF IN-SERVICE, FULL-DEPTH PRECAST CONCRETE DECK PANELS TO CAST-IN-PLACE DECKS PI: David Garber Graduate Research Assitant: Esmail Shahrokhinasab Undergraduate Student Intern: Josef Ricardo

“The comprehensive study by Dr. Garber of the performance of full depth deck panels will help bridge owners select the appropriate deck system for their ABC projects.” Ahmad Abu-Hawash, Chief Structural Engineer, Iowa DOT

OBJECTIVE:

Determine (1) the in-service performance of full-depth, precast concrete (FDPC) deck panels compared to conventional cast-inplace (CIP) decks through and (2) successful and problematic details for FDPC deck panels and connections.

SYNOPSIS:

Full-depth, precast concrete deck panels have been heavily used in bridge construction since the 1970’s. The use of these panels has traditionally been thought to both accelerate construction and improve the long-term durability performance of the bridge deck. While many engineers and academia are intrinsically aware that conﬁned precast can perform equally or better than no conﬁned, cast-in-place concrete, evaluation between the two has never been studied holistically. The main objective of this project was to determine the in-service performance of full-depth, precast concrete (FDPC) deck panels compared to conventional cast-in-place (CIP) decks. The secondary objective was to determine successful and problematic details for these members. A survey was developed and distributed to state DOTs. Survey responses were used to develop the FDPC Deck Panel Database, which was then used with LTBP InfoBridge to determine the performance of bridges with FDPC deck panels and similar bridges with CIP decks.

DEVELOPMENT OF PREFABRICATED BRIDGE RAILINGS PI: Terry Wipf Co-PIs: Sri Sritharan, Brent Phares Graduate Research Assistant: Ashley Ecklund

“The significant potential of the developed barrier details to accelerate bridge construction nationwide prompted Iowa and several other states to undertake a crash test on the proposed system through a pool fund project.” Ahmad Abu-Hawash, Chief Structural Engineer, Iowa DOT

OBJECTIVE:

Develop prefabricated concrete bridge barriers with dependable connections. The connections were designed with considerations such as, constructability, durability, easy repair, minimal damage to deck, and cost.

SYNOPSIS:

Many transportation organizations have embraced Accelerated Bridge Construction (ABC) to reduce both the trafﬁc impacts and societal costs. One of the most common means to achieve ABC is to utilize prefabricated elements that are connected on site to construct a bridge. ABC will not be effective if bridge barriers require cast-in-place construction. The purpose of this report is to present details of a precast barrier and two connection alternatives between the deck and precast barriers. In addition, a new connection between two adjacent prefabricated barriers is presented. All three connections were tested using full-scale precast barriers and a video summarizing the test can be found at https://youtu.be/up6sMEeqfaU.

ABC-UTC 2017-2018 HIGHLIGHTS

One barrier-to-deck connection used inclined reinforcing bars with threaded ends that were connected to bar splicers embedded in the bridge deck. The other barrier-to-deck connection used U-shaped bars that were inserted into the barrier from the underside of the bridge deck overhang. Factors that were considered when designing the connections were minimal damage to deck, easy replacement of barrier, constructability, durability, and cost.

The barrier-to-barrier connection utilized headed reinforcement in the longitudinal and transverse directions. The connections were designed to meet TL-4 loads as per the Manual for Assessing Safety Hardware (MASH) and Load and Resistance Factor Design (LRFD) Bridge Design Speciﬁcations. This report presents results from various tests and shows that all proposed connections are viable for accelerated construction of concrete barriers, although some reﬁnement to the tested details are recommended.

DELIVERABLE:

Laboratory-tested design details for F-shape prefabricated bridge rails with two barrier connection systems. The resulting bridge deck and prefabricated barrier after testing was completed.

AN INTEGRATED PROJECT TO ENTERPRISE LEVEL DECISION MAKING FRAMEWORK FOR PRIORITIZATION OF ACCELERATED BRIDGE CONSTRUCTION PI: Alice Alipour Co-PI: Doug Gransberg Graduate Research Assistant: Ning Zhang

“Utilizing a holistic approach and considering the impact of bridge replacement techniques on the transportation network will aid in the decision making process when considering ABC” Ahmad Abu-Hawash, Chief Structural Engineer, Iowa DOT

OBJECTIVE:

Development of i) an enterprise-level decision making framework by simulating the transportation network of the region under consideration, deﬁnition of the performance measures, identiﬁcation of critical facilities, social effects, economic impact to business/ industrial districts in the region for prioritization and ranking of the ABC bridge candidates, and ii) a matrix-based project-level decision framework consisting of important indices (such as time, cost, or safety) that affect the outcome of the project in terms of time and constructability

SYNOPSIS:

Accelerated bridge construction (ABC) techniques are rapidly gaining acceptance as an alternative to conventional construction to reduce construction duration and minimize the impact of closures at the network level. There are different types of ABC and each technique has its limitations and speed of completion. The choice of using a specific ABC depends on a host of different factors including its applicability to specific bridge site, criticality of the bridge to the network, and availability of capital funds for its implementation. Some of these factors tend to have contradicting affects, as a faster ABC technique often entails higher investment levels; on the other hand, a faster technique for a bridge with high criticality to the network may result in large savings in user costs. Holistic decision making framework using quantifiable measures. The framework not only considers the project level factors in choice of ABC techniques but also goes beyond the physical borders of a specific project and considers the regional effects that a specific bridge could have in the everyday life and long term growth of the region.

INTEGRAL ABUTMENT DETAILS FOR ABC PROJECTS, PHASE II PI: Travis Hosteng Co-PI: Behrouz Shafei Graduate Research Assistant: Austin DeJong

“This research undertaken by the ABC-UTC is leading to details for integral abutments that can constructed in an accelerated fashion satisfying both our need for speed and long-lasting, low maintenance durability. “ Jim Nelson, State Bridge Engineer, Iowa DOT

Design, test, and analyze three connection details for ABC of Integral Abutments. These have details per the Iowa DOT and are to replace the typical cast-in-place connection of integral abutment construction. The three connection details include Grouted Reinforcing Bar Couplers, Pile Couplers, and a UHPC-Joint. They will connect the integral diaphragm to the bridge pile cap and develop sufﬁcient strength to allow for trafﬁc in 1-5 days, instead of curing time of at least 7 days for the cast-in-place. Testing and analysis of the connections are compared to the results of Phase I testing and analysis of the cast-in-place control connection detail.

SYNOPSIS:

Accelerated Bridge Construction (ABC), is growing in popularity within the bridge community and is gaining traction for research projects to investigate how the construction of bridge elements can be expedited. One such element being investigated is the integral abutment. The integral abutment alleviates the need for the expansion joint by having the superstructure rigidly connected to the foundation to cause the two elements to act together in response to trafﬁc loads as well as thermal expansions and contractions. In addition to the reinforcing congestion, the construction tolerances and weight of the integral abutments cause some problems for ABC projects. These issues were the basis for this project to investigate the use of couplers and ultrahigh performance concrete, while applying ABC techniques. The foundation element of focus was the pile cap, and the superstructure element investigated was the integral diaphragm, which consists of the deck and cast-in-place beam. The strength and durability of the connection details were evaluated through full-scale laboratory testing that applied simulated thermal loads and live loads. The results of these tests were compared to the control specimen tested in Phase I, as well as comparing the revised designs in Phase II to the original designs from Phase I.

SHAKE TABLE STUDIES OF A BRIDGE SYSTEM WITH ABC CONNECTIONS PI: M. Saiid Saiidi Co-PI: Ahmad Itani Senior Personnel: Mohamed Moustafa Graduate Research Assistant: Elmira Shoushtari

OBJECTIVE:

Investigate the seismic performance of a large-scale two-span bridge system that integrates some of the more promising ABC connections. The speciﬁc objectives of the project are to determine constructability issues related to assembling bridge components and connections, interaction among bridge components, effect of combined gravity and bidirectional seismic loading on ABC connections, and adequacy of emerging seismic design guidelines for ABC connections.

SYNOPSIS:

“Shake table validation of the seismic performance of prefabricated bridge elements and their connections will allow engineers to confidently design resilient bridge substructure systems that may be rapidly constructed provide enhanced seismic performance and improve postevent serviceability. “ Elmer E. Marx, Senior Bridge Engineer, Alaska Department of Transportation and Public Facilities

Connections between prefabricated elements in ABC bridges are critical in high seismic areas to maintain the integrity of the bridge system. Various ABC connections have been investigated at the component level. However, to confidently recommend ABC bridges for adoption in standard bridge design and construction, they should be tested as a system. This study aimed at addressing this issue by conducting experimental and analytical investigations of a 0.35-scale twospan steel girder bridge system with six ABC connection types: (1) column-to-footing rebar hinge pocket connection, (2) column-tohybrid cap beam grouted duct connection, (3) steel girder-to-cap beam connection, (4) girder-to-deck grouted pocket connection, (5) ultra-high performance concrete (UHPC)-filled joints between the deck panels, and (6) UHPC-filled joint over the pier. The bridge system was tested to failure on shake tables under successive motions simulating scaled versions of the 1994 Northridge-Sylmar earthquake. Results demonstrated that the performance of the bridge model was comparable to cast-in-place bridges.

DELIVERABLE:

2) Seismic testing of a 2-span bridge model using shake tables and instrumentation plans and protocol developed in this study. 3) Developing a reliable analytical model for simulation of the inelastic seismic behavior of ABC bridge systems. 4) A report summarizing the key activities and conclusions regarding component versus system performance, interaction among different components, and variation of load path under different limit states.

Children are often more impacted by how they play and what they do at home than what they learn in school. For this (and many other) reasons, there is an incredible beneﬁt to including parents in activities with their children.

The ABC-UTC and FIU’s Education Effect sponsored a parent/child summer camp for students in 3rd to 5th grade and their parents on June 19th to 21st, 2017. The camp allowed the children and parents to work through several bridge engineering-related activities together. Participants were all given a bridge building toy to encourage the continuation of these activities at home.

Parents and their children participate in several activities, including the construction of paper and balsa wood bridges and the decoration of a 3D printed bridge.

ABC-UTC 2017-2018 HIGHLIGHTS

The ABC-UTC hosted its second annual Parent/Child Bridge Engineering Summer Camp at FIU on June 13-15, 2018.

ISU’S GO! E-ZINE FOR TEENS Go – ABC! aims to develop the future transportation workforce by educating and stimulating young minds about ABC. In 2016 the ABC-UTC consortium of universities continued Go! Postings on ABC-related articles for teens through the E-zine for Teens online magazine.

Posted on April 2017 by Armin Mehrabi, PhD, P.E. We’ve all experienced traffic jams and slowdowns in road construction zones, and we all hate it. They waste our time, create a bigger carbon footprint, and cause safety concerns both for the workers as well as the drivers. This becomes an even bigger issue if the work is on a bridge. That’s because bridges are normally built to cross over a natural barrier—like a river or cliff—or to avoid major traffic crossings. In both cases, if the bridge is closed, drivers may need to travel tens of miles out of their way to find another crossing. Sometimes traffic interruptions are just plain unavoidable. But with good planning and smart solutions, you can avoid them all together (or at least reduce them).

QUARTERLY GRADUATE STUDENT SEMINARS

Web-based Graduate Student Seminars were initiated by the ABC-UTC in January 2016 as part of its workforce development focus area. These quarterly seminars continued through the ﬁrst quarter of 2017 to highlight graduate students’ contributions to the ABC research projects in which the students worked. Beginning with the second quarterly seminar in 2017, the seminars were restructured and renamed “Research Seminars,” each with focus on one ABC-UTC research project. The featured presentation is now given by the project’s principal investigator(s) and the graduate student(s) working on the project. Each seminar provides an overview of the ABC-UTC research project and the tasks covered in the project, including the student’s work on those tasks, and continues the strong emphasis on the ABC product(s) coming out of the research project for implementation. Each seminar is one hour in length and consists of a 40-minute presentation followed by a 15-minute question-and-answer session. See Research Seminar Archives (https://abc-utc.ﬁu.edu/webinars/research-seminars-archives/) for additional details.

ABC Project Database

ABC Research Database

WEBSITE Enhancements to the ABC-UTC website (https://abcutc.fiu.edu) continued in 2017-2018, with additional ABC information posted to assist bridge professionals in successfully using ABC technologies in bridge replacements and new construction. You are invited to let us know additional resources that could benefit you in your implementation of ABC. For example, initiated in 2017 and further developed in 2018, “Implemented Advanced Technologies” are innovations that could provide benefit if included in an ABC project. The intent of this initiative is to provide readily available details on these technologies to assist bridge owners and designers in better understanding the technologies. To be listed on the website, the technology must have been included in at least one project posted in the ABC Project Database and have been presented in an ABC-UTC monthly webinar featured presentation. See https://abc-utc.fiu.edu/resources/ implemented-advanced-technologies/
