摘要：

A refined second-order method is presented for structural reliability analysis. Exact and approximate reliability solutions are obtained for a circular shaft subject to random bending moments and a random torque. The comparison of the approximate results with exact ones shows that the first-order approximation is only applicable to the case where the failure surface is ''far'' from the origin, while the suggested second-order approximation yields quite accurate results even if the failure surface is ''close'' to the origin.
