Approximating sensitivity of failure probability in reliability-based design optimization

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).Non UBCUnreviewedThis collection contains the proceedings of ICASP12, the 12th International Conference on Applications of Statistics and Probability in Civil Engineering held in Vancouver, Canada on July 12-15, 2015.
