Abstract：Using particle swarm optimization algorithm with stochastic inertia weight (SIWPSO), the optimal program was compiled in MATLAB. The force conditions and the boundary conditions were inserted to obtain exactly optimal parameters of cellular beam under any condition. The results show that after a mass of debugging and FEM validation, it is found that the program is stable, and the models with the parameters from programming have admirable mechanical properties. With fast convergence and high precision, the SIWPSO algorithm can save designing time and meet the design requirements. The cellular beams from the algorithm can resist external forces with less steel to obtain good economy. The algorithm is highly suitable for designing cellular beam.
