| Abstract: | The alternative algorithm based upon negative gradient vector is proposed in the paper for calculating the structural reliability index, and which has eliminated the shortcoming of the first order second moment method, and has been effective in nonlinear performance function. The numerical results show the better characteristics of this method are accurate in calculation, with better convergence and procedure to be gained. |
