Reliability-based structural optimization using sequential response surface method
A design method of reliability-based structural optimization has a powerful advantage because some random variables can be considered.However,the sensitivity analysis of reliability with respect to random variables is very complicated and its computational cost is very expensive.Thus,a response surface method is adopted for approximating the limit state function to improve computational efficiency.An iterative strategy is used to determine a response surface that is able to fit the limit state function in the neighborhood of the design point.A sequential response surface method is performed to satisfy the demand of accuracy in the process of reliability-based structural optimization.A numerical example is presented to demonstrate the computational efficiency of the proposed method.
