In this paper optimum design of structures for earthquake loading was achieved by simulated annealing method. The evolutionary algorithm was employed for optimum design of two space structures. To reduce the computational work, a discrete wavelet transform (DWT) was used. In DWT the number of points in the earthquake record was decreased with Mallat Method. A dynamic analysis of time history was carried out. By DWT the earthquake signal was decomposed into a number of points. Then the two space structures were optimized for these reduce points. The actual responses were reconstructed with a reverse wavelet transform (RWT). A number of space structures were designed for minimum weight. The result show, DWT and RWT were an effective approach for reducing the computational cost of optimization.
