Structural Grid Predesign using Generative Design for Residential Building with Steel Structure on BIM Models - Structural grid predesign using generative design

Due to the more significant architectural complexity, it is helpful to include structural analysis studies in the early design stages. An architectural team typically carries out the structural grid fit in this phase. This limitation may lead to the structural distribution in the initial phase not being the most appropriate. This work aims to provide a tool for architects oriented design by optimising the cost of the structure, making an initial layout for residential buildings with the regular shape of steel structures using the generative design, which allows the creation of structural BIM models that comply with the requirements of stability and resistance for gravity design specified in the American code ASCE 360 as starting point on the conceptual design. The paper describes the computational design development for the structural building grid using multi-criteria optimisation solved by a genetic algorithm.
