Abstract

The authors have proposed a new practical optimal design method called the statistical optimization method, which consists of the following five steps : the effectivity analysis, reanalysis, evaluation of dispersion, the optimization and evaluation of structural reliability. The design of experiments, combined with a series of finite element analyses (FEA), is used to generate approximate evaluation functions for the controlling behavior depending on the changes in design variables of an object structure. The evaluation functions can also be used as direct tools for estimating the characteristic behavior of design structure. First-order second-moment method is employed to evalu
