Research Paper


Steel pitched roof frames with the tapper fabricated members is the common solution for a wide range of industrial structures. In the present research, design optimization of the steel member sections is performed by different apex heights and tapered lengths for steel pitched roof frames. The effective variable definition has helped to reduce the variable domain and ignore the unwanted part of the bounds before starting the optimization process. Nine metaheuristic algorithms are used for the optimization. Results show that selecting apex height and tapered length can change optimum weight of structure by 10%. Additionally, performance of the considered metaheuristic algorithms is compared for this type of frame structures.
