Method for Designing Prequalified Connections Using Generative Design

Designing prequalified connections is a process of iterative calculation, in which certain dimensions are varied until the verifications and restrictions stipulated by the standard are met. This is a slow process that can be automated using various software and optimized using a new design method called generative design, which consists of establishing restrictions so that the script delivers multiple solutions that meet the objectives. This research was conducted based on the design science research (DSR) methodology and focused on developing a method to design moment-resisting steel connections, specifically end-plate connections, using generative design in a building information modeling (BIM) environment. From this, it was possible to obtain several end-plate connection design alternatives, and technical validation was carried out to verify the functionality of the program using a verification method proposed by a civil engineer.
