Study on FEM Analysis of Multistory Steel Frame Structure and its Optimal Design

Abstract:

An finite element model (FEM) of multistory steel frame structure is established by applying ANSYS parametric design language(APDL) in this paper, where the objective function of optimization is defined as the minimum volume of a Pin framework. The optimal design are carried on by applying the optimized toolbox of ANSYS, based on analysis the situation of the most disadvantageous load combination. Several approaches have been proposed to avoid restraining to the local minimum. Experimental results show that the section size of the structural element improved obviously.
