Abstract

This study investigates a new metaheuristic method called symbiotic organisms search (SOS) for sizing optimization of steel truss structures. The design constraints are adopted from SNI 1729:2015 Indonesian code specification for structural steel buildings that includes the constraints on slenderness ratio and force capacity. Five practical case studies of truss design are employed to test the performance of the SOS algorithm. The simulation results of the SOS are compared to other metaheuristic methods, namely, the particle swarm optimization, differential evolution, and teaching learning-based optimization, in terms of accuracy and consistency. The results show the superiority of the SOS as well as excellent convergence behavior over the other metaheuristic algorithms in solving the truss structure optimization problems.
