To design a more economical structural form, it is nec essary to optimize both the topology and shape of struc tures. To optimize topology, we propose a hybrid of Ge netic Algorithm (GA) and Evolutionary Structural Opti mization (ESO). This paper describes the considerations in applying the proposed method to topology structural optimization. Through numerical examples, the proposed method showed better search ability than GA or ESO meth ods alone. Moreover, this hybrid method makes it possible to design a more economical structural form.
