A hybrid Kriging-based reliability method for small failure probabilities

The main goal of structural reliability is to determine the failure probability of a structure by considering the randomness of the inputs. When the failure probability is small, the simulation methods may have high computational costs, especially for complicated and time-consuming numerical models. In this paper, a modified algorithm based on Monte Carlo simulations and the Kriging metamodel (AK-MCS) is proposed. The strategy is to replace the...
