摘要: The second-order reliability method (SORM) is an effective tool to evaluate the reliability, but its application for reliability-based design optimization faces unbearable computational cost. In this study, a new hybrid sequential approximate programming (HSAP) developed calculate optimum efficiently by developing distance-checking criterion and convex method. Since identifies feasibility of probabilistic constraint effectively, proposed combines efficiency accuracy SORM. also constructed using sensitivity function value constraint. So no additional cost required in process. Five illustrative examples, including two mathematical examples thee practical engineering demonstrate HSAP.
