Street Space Study

Project Information Location : Princes Highway, Springvale Victoria, Australia Level

: 8-level (including basement)

Site area : 4000M2 Function Space: Carparking, Food court, Movie Studio, Class rooms, Display rooms, Galleries, Fun houses, Childcare centre.

At the beginning of the project, a street of the site was conducted via site visit and online map. Based on the land survey results, the boundary conditions of the site and surrounding environment were explored for the following design use.

Concept Study Based on the learning of surrounding environment, a feasibility study illustrates that a multilayers commercial complex is a comparatively acceptable choice. Therefore, the project is to be designed as 8-level commercial complex at this stage.

The concept of the proposed design arises from a flying car. The flying status provides people inside it with a fantastic view of surrounding environment and exciting feelings. The suspension structures (connected by inclined columns and suspended cable) could be viewed as its products, which are pretty popular among commercial complex.

Level 3 provides the activities specially for children. Classrooms, office rooms and play area distribute at this level to provide the services for them.

Level 4 is a great representative of suspension ideas of the building. Caretakers residence is the only function space at this level. Elevator, inclined columns and light well could be seen clearly with strong visual impact. In ground level, the drive way to basement car parking is located on the western side of the building. 16 Childcare parking space is also provided above the ground surface on the eastern side of the building. To provide the most convenient services, the ground level also provides the space of food court, convenience store and medical centre which could provide essential aids for upper-level childcare and customers.

Architectural Renderings To provide the client with a vividly and understandable plan, a 3D model of the proposed project was created by using SketchUp and the corresponding rendering was made. View No.1 shows the top view of the light well, which is a significant component for natural lighting and the columns at corners of the well are the main supporting element in the building. View No.2 gives a clear view of the façade of the building, which looks like a flying bird. The rest of rendering pictures also help the client understand the structure and spatial constitution.

Building Information Modelling & Virtual Reality This project is to create a Revit model of an Engineering Building in the University of Melbourne. Based on given floor plans and guidance, a 6-soty model including the discipline of Architect, Structural and MEP was created. After finishing modelling, the structural analysis was conducted by using Autodesk Robot and the cost estimation was conducted by using CostX.

Project Information

Site Study

This project is part of the content of Integrated Design, which requires redesign the structural part with acquired knowledge of the existing Cancavo apartment. At the beginning of the design, a site visit was conducted, thus, the original elements and function rooms’ distribution were studies clearly. Based on the plans provided by Robert Bird Group, the structural system (concrete frame structure with band beams) was proposed at the beginning.

Location : Convesso Concavo , Docklands, Melbourne, Victoria

Floor Plan (Structural) Based on the given floor plans (Architect), site visit results and the reference from Guide to Long-Span Concrete Floors (2nd Edition) 2003,Cement and Concrete Association of Australia, the distribution of beams, columns and concrete core are determined in the plan. The original dimensions of components were determined based on AS 3600 and the Guide. Furthermore, to make an economical plan, the features of elements such as shape and dimension at different height vary significantly.

Load Distribution Plan According to AS 1170, different load cases were allocated on the floor plan based on their functionalities. After the estimation of the subsidiary area, the representative load acting on columns were determined and five critical columns were designed as examples so that the process could be reasonably simplified. The figure shows the location of one of these columns (Podium No.2). Page 4 of 11

Load Rundown

Structural Elements Design Beam Design

Column Design

This part includes the design of beams, columns, slabs and connections. To find the relatively proper column sections, load rundown was conducted and the most economical sections were determined, and these sections could also meet the capacity required in the AS 3600. For beams and slabs, not only the capacity should be checked, but also the serviceability needs to be considered as well.

Columns Cross Sections According to AS 3600, the initial dimension was estimated. Considering the self-weight and adding-on loadings, the load rundown was conducted to check if the dimension and concrete grade is proper to provide enough support. Accordingly, the amount of reinforcement could be determined as well. Then, based on the Reinforcement Detailing Handbook For Reinforced and prestressed Concrete 2010. Concrete Institute of Australia, the structural drawings of these columns were finished, which is shown above.

Beam Sections and Elevations Similarly, the capacity of beams will be designed to meet the standards specified in AS 3600. Due to the long span of the beams, prestress reinforcement was introduced into the structural system. This also is part of the consideration of deflection minimization, as the slab and beam design not only should consider the capacity design, but also the serviceability. Then, based on the Handbook, the structural drawings of the elements were finished, which is shown above. Page 5 of 11

Apart from the medical clinics in stage A, a 240M2 convenience shop is proposed

Project Stage B

Project Overview •

Determine the layout of the structural members under given conditions

Structural modelling and analysis using Space Gass (under wind & earthquake load) Finite Element Analysis of the slab using Strand 7

Finite Element Analysis (Restriction No.1) Partial floor plan of the high rise building is selected to conduct the Finite Element Analysis. With the first type restriction, the floor acts as a simply supported beam and the corresponding strain distribution is shown as above. The significant deflection appears at both beam and slab.

Space Gass Modelling & Analysis

Create a 44-story concrete high rise building model using Space Gass Model A is the core system without header beams

Model B is the core system with header beams

Compare the deflection at the top of the two models Compare the base forces of the two models


Finite Element Analysis (Restriction No.2)

Through comparison, it is obvious that the moment of each column with header beams is smaller than that without header beams. The presence of header beams effectively integrates lateral load resisting components in the structure. With the aid of coupling action, the lateral resisting ability of structure is significantly improved as well.

When considering the restriction from a beam, the significant deflection only appears in the middle of the slab and the stress distributions vary even under the same acting loads. Page 8 of 11

Structural Analyses (Earthquake & Wind) In high-rise buildings, wind load is the dominant effect among all type of actions, especially in coastal and cyclone districts. To get the effects result from wind load, pressures acting on the building are determined based on AS 1170.2. It should be noticed that, the wind speed varies significantly in different height. Furthermore, the seismic effect is another important factor needs to be considered. As structures could be damaged during a strong earthquake due to the whipping effects. For analysis, even the time-history method is the most accurate one to calculate earthquake effects, to simplified the design process, equivalent static analysis method is adopted in this project.

5. Concrete form

Machining on site could largely facilitate the framing process and save materials

Before the installation of roof truss, extra braces are needed to resist lateral forces

Steel beams are normally used in garage due to its long span

Holes need to be reserved for service pipes and the opening should be sealed during constructions

Concrete form should be fixed properly to avoid collapse during pouring concrete

During the study on construction site, the understanding of structural design theories was further strengthened, especially the content in AS 1684 and Building Code of Australia.

On-site handle work also enabled me to combine the knowledge with practical experience.

The practical construction experience will contribute to a more reasonable, economical and comfortable residential projects design.
