This study describes a simulation method to estimate structural failure probability using “all quadrants sampling method” and the variance reduction techniques of “partition of the region.” Every time a real sample point is generated in a certain quadrant, pseudo samples corresponding to the real sample are determined in all other quadrants by applying previously proposed “inter-quadrant relational expression.” By using all of real and pseudo samples in the estimation of the structural failure probability, the sampling efficiency is increased. Numerical examples to estimate the structural failure probability show that the proposed method gives accurate estimations efficiently.
