Scaled Charged System Search Algorithm for Optimum Design of Steel Frames

With increasing demand for large scale and complex structural models, optimum design has become a challenging and important issue in structural engineering and meta-heuristic algorithms have become powerful tools for optimal design of structures. Charged System Search (CSS) is one of the meta-heuristics, inspired by the governing laws of electrical physics and the Newtonian mechanics, Kaveh and Talatahari (2010). CSS based optimum design of structures needs adjustments for variable based and problem based constraints. The first adjustment guarantees to select from predefined cross sections and as a result, all specifications of sections will be ready to run the analysis and the second one helps to find the optimum design in fewer steps.
