In this study, the impact of connection topology and soil-structure interaction on the optimal design of steel space frameworks is
investigated. To introduce seismic load in the MRSF structures, horizontal lateral load is applied to the floors of the steel frames using
the equivalent lateral load method. A comprehensive three-parameter elastic soil model is employed to examine soil's effects. The
teaching-learning-based optimization (TLBO) and particle swarm optimization (PSO) are utilized in the optimization process. The
optimization process includes stress and strength limitations as specified in the AISC-ASD and AISC-LRFD rules, serviceability, and
geometric restrictions. A software developed using the C# programming language implements metaheuristic algorithms. The software
interfaces with
SAP2000 using the Open Application Programming Interface (OAPI). The method's efficacy is illustrated by analyzing various
examples and substantiated by existing literature findings. The results indicate that the configuration of connections and the
interaction between the framework and the soil substantially impact the response of structural elements, ultimately increasing the
frame's overall weight.
