Structural optimization in order to reduce costs associated with design and implementation always has been desired by engineers. Thus, the production of structural honeycomb beams with higher strength and lower cost since 1950 has been considered by engineers. Among the main features of these beams can be pointed to architectural features and height which resulting in greater strength and stiffness of the beams without the added weight of the beams. In this study, the overall cost is considered as objective function to optimization, also the effect of welding and cutting parameters is investigated. Due to (AISC_ASD) regulations, required limits are intended in design of beams. Finally, on terms of design variables and constraints, optimization of the beams using particle swarm algorithm is presented with an example.
