Optimum Design of Castellated Beams Using the Tug of War Algorithm

In this chapter, the tug of war algorithm is applied to optimal design of castellated beams. Two common types of laterally supported castellated beams are considered as design problems: beams with hexagonal openings and beams with circular openings. Here, castellated beams have been studied for two cases: beams without filled holes and beams with end-filled holes. Also, tug of war optimization algorithm is utilized for obtaining the solution of these design problems. For this purpose, the cost is taken as the objective function, and some benchmark problems are solved from literature (Kaveh and Shokohi [1]).
