Abstract

Rebar layout is crucial for structural integrity, cost efficiency, and accurate estimation in construction. This paper presents advanced algorithms for optimizing rebar cutting lengths and automating structural drawings. Utilizing structural design outputs, the approach integrates special length rebar concepts and shape codes for precise bend deductions. Algorithms were developed to calculate rebar lengths for structural elements like columns and beams, addressing longitudinal continuous, discontinuous, and confinement rebars. This resulted in a 10.56% reduction in column rebar quantities and a 2.22% reduction for beams compared to the original design. Automated rebar layout algorithms also established equations for determining rebar coordinates and arrangements, facilitating efficient structural drawing generation. This reduces manual drafting, streamlines rebar workflows, and enhances project efficiency. The findings highlight the potential of computational techniques in rebar layout optimization, enabling cost-effective, sustainable construction practices while improving accuracy and efficiency.
