The developed method combines optimization-based and simulation-based approaches. The proposed approach consists of two major parts. In the first part, an optimization-based method is used to search for the most probable point (MPP) on the limit state. This is achieved by using an adaptive response surface constructed through an optimal symmetric Latin hypercube design of experiments and a trust region update approach. In the second part, a multi-modal adaptive importance sampling method improves the reliability estimate, using the MPP information from the first part as the starting point. A generalized framework for reliability estimation is then established for problems with a large number of random variables and implicit limit states.
