In this chapter, some meta-heuristic algorithms consisting of particle swarm optimization, colliding bodies optimization, and enhanced colliding bodies optimization are used for the optimization of semi-rigid jointed composite castellated beams. Profile section, cutting depth, cutting angle, holes spacing, the number of filled end holes of the castellated beams and rigidity of connection is considered as the optimization variables. Constraints include the construction, moment, shear, deflection and vibration limitations. Effect of partial fixity and commercial cutting shape of a castellated beam for a practical range of beam spans and loading types are studied through numerical examples. The efficiency of three meta-heuristic algorithms is compared.
