Automation and Optimization Tool for Efficient Shear Steel Connection Design

Abstract

This study proposes an efficient optimization tool for five commonly used shear steel connections. Using metaheuristic algorithms, the tool evaluates numerous design options for all shear connections in a structure, suggesting the most economical design options considering material and fabrication costs, as well as constructability constraints. Implemented in Tekla Structures, a commonly used building information modeling software in the steel fabrication industry, this tool automates the design and optimization of a broad range of shear connections. It allows for adjustments based on user preferences and customization for different steel fabrication practices. To assess the tool's effectiveness against real-world designs, two case studies were conducted on 2- and 5-storey steel buildings. These studies showcased the tool’s potential to generate more economical connections in significantly shorter time frames, confirming its applicability, efficiency, and potential as an alternative to conventional connection design procedures in the steel industry.
