Abstract

Abstract

The man-made material is added around optimal structural cavities and boundaries. Based on evolutionary structural optimization (ESO) method and element strain energy analysis, a structural topology optimization method was developed with strain energy analysis. The basic theory of topology optimization was given, and the formulae of ESO method with the function of removing and adding elements were derived. Simulation designs of bridge pier and bridge structure with isotropic material were completed by the proposed method. Simulation results show that the difference between the maximum and minimum strain energy remarkably becomes little, and the topology structures are similar to the ones in engineering, which indicates that the basic principle of the proposed method is feasible for structural topology optimization.
