AB - <p style="text-align: justify;">Optimum design of structures is achieved by genetic algorithm. The
evolutionary algorithm is employed to design structures. The method
improves the computing efficiency of the large-scale optimization
problems and enhances the global convergence of the design process.
The loads are considered as earthquake loads. A time history
analysis is carried out for the dynamic analysis. To decrease the
computational work, a wavelet transform is used by which the number
of points in the earthquake record is reduced. A reverse wavelet
transform is also employed to reconstruct the functions under
consideration in the time domain. A number of space structures are
designed for minimum weight and the results are compared with exact
dynamic analysis.</p>
