| Abstract: | In this paper, the improved BP algorithm combined with the method of improved point estimation is used to compute the characteristic probability in the nonlinear stochastic structural analysis.By the method of weighted residuals the reliability of the unstability of the closed cylindrical shell with both ends built-in is calculated. Results show the validity of the present method. |
