Pursuits of continuous innovation and shortening of development costs are inevitable challenges in contemporary society, so the structure should be designed to creative thinking, along with excellent flexibility and efficiency, innovation and implementation. This study investigated the structural characteristics of AOI structures with aluminum extrusion and square steel, using finite element analysis to explore the structural analysis for structures with different sections of aluminum extruded shape and square steel, understanding its static analysis and modal analysis, and the results of finite element analysis are the main bases for the future development and subsequent research.
