Optimization of a large steel truss structure used in civil engineering, by Finite Element Method

摘要

This paper presents the optimized version of a steel structure used in civil engineering obtained thru a process of structural optimization using Finite Element Method. The main advantage of this optimized structure is the cost which is 50% smaller then the cost of a standard version of this steel structure. The optimization process was made using Finite Element Method and Ansys program. The paper presents the results of structural analysis of this optimized steel structure in two load cases: the snow weight and the seism simulation.
