摘要：
A reliability sensitivity analysis method for structural system with multiple failure modes is proposed. For arbitrarily distributed random variables, the perturbation technique and the Edgeworth expansion are employed to approximate the cumulative distribution function of each failure mode. The reliability of the system is then calculated based on reliability theory. Reliability sensitivity of random variables are derived with the gradient method.
