In this paper, the authors present a new evolutionary optimization method for three-dimensional structural statics. The method consists of two optimization processes in series. The former process in to deal with the topology optimization. The latter process in to deal with the configuration optimization. The method finds an approximate optimum topology and configuration of the structures from any initial design of them : That is, an optimum structure design can be obtained from a simple and small initial structure. Therefore, less computational cost and time will be required to obtain results by the method than those by conventional ones.
