By coupling the importance sampling with simulation method based on the conditional expectation, generated samples are effectively made use of estimating the structural failure probabilities with smaller coefficient of variation. Numerical examples results based on the proposed method are compared to those based on other simulation methods and the proposed method results in making the estimation process of structural failure probability more efficient, reducing the dimensionality of structural reliability assessment problem and expediting convergence.
