Abstract

This paper presents an efficient numerical method for approximating the parameter sensitivity of the failure probability with respect to design parameters. The method is computationally inexpensive and the obtained approximations are more accurate than the approximations based on first order reliability method (FORM). The method is particularly suitable for applications in reliability-based design optimization (RBDO), including reliability-based topology optimization (RBTO).
