Automated Structural Design Optimization for Reinforced Concrete with BIM

The Structural design optimization for reinforced concrete has been executed for several decades. The technique plays a significant part in maximizing the consistency, cost-efficacy, and environmental sustainability of RC structures. Nevertheless, the optimizing Rebar Concrete structural design is a bit challenging and entails innovative approaches during the diverse life cycle of RC structures.

Research Undertaken in RC Structural Design Optimization

The last few decades have seen the extensive researches in the RC structural design optimization, though there is a dearth of the comprehensive assessment of the endeavor. Hence, a critical evaluation of the earlier research about the Structural Optimization of Reinforced Concrete is conducted by the experts for reducing the number of construction materials, material cost, and environmental effects, with emphasis on a detailed design like steel reinforcement, to identify the research themes and highlight the future directions.

Need for Implementng Clash Mitigated Rebar Design for Structure

Based on the critical evaluation, the need has been identified for the implementation of clashmitigated rebar design optimization, detailed design optimization of intricate Rebar Concrete components, and the application of the design for manufacture & assembly.

Challenges of Manual Rebar Design Process

The steel reinforcement detail design of Rebar Concrete structures is one of the significant aspects of construction. Despite the introduction of advanced technologies in the Architectural, Engineering, & Construction domain, the rebar design process is mostly accomplished by the manual or semi-manual approaches, with the software packages following the regional design codes. A manual process leads to conservative, indefinite, and improper consequences. Furthermore, the simple design of the RC structural elements can face constructability issues like congestion, collision, & complexity causing complications during the procurement of rebars and other facets all along with the construction phase.

The consequence of the Manual Process- Enhanced Construction Cost & Time

The challenges also deter concrete pouring. Hence, improper compounding of concrete with the rebars gets generated upsetting the veracity of the RC structure. These concerns considerably enhance the construction cost and time and are extravagant for the AEC project stakeholders. Even if earlier studies have conducted the detailed design optimization of RC structures, little attention has been provided to these challenges.

Holistic BIM Methodology using Meta-heuristic Algorithms

A holistic BIM-based approach uses the various meta-heuristic algorithms like SGA, SGA-SQP, & PSO-SQP for the optimum detailing & designing of RC slabs, for reducing the construction cost. The prime objective is to determine the reduced construction cost of the Rebar Concrete slab, along with the cost of steel reinforcement bars in reinforcing layers, cost of concrete, and labor cost for steel reinforcement bar installation and concrete pouring in the RC solid slab.

Process of BIM Optimized Structural Engineering

The process of BIM optimized structural engineering should be managed in such a way that the first stage can augment the steel support present in all the 4 reinforcing layers (including two layers at the bottom & top of solid slab), whereas the second stage can improve the solid slab thickness as per the concrete strength.

Optimum Design Solution with BIM Model for Structural Detailing

To make the optimum design directly constructible without any further modifications, available standard rebar diameters, space requirements of the rebars, appropriate regional design provisions, and constructability with clash avoidance concerns are merged into the development of the BIM optimizated model, which can be used as a design tool for retrieving cost-effective design solutions

at an earlier stage of structural detailing design.
