| 摘 要： | 本文从计算构件结构可靠度的几何法出发,给出了构件可靠度对随机变量的数学特征及对极限状态方程参数灵敏度的计算方法,并通过算例说明了对同一构件,在采用不同的权限状态方程时,虽然其可靠度指标相同,但可靠度指标对随机变量的灵敏度却有较大的变异性.

| Abstract: | The calculating method of sensitivity of structural reliability to variates, including its numerical characteristics and the parameters of limit state equation. was conducted. starting from point of geometric method for calculating to structural reliability. It is explained through the example that the sensitivity of reliability index to variates has much difference when different limit state equations are used, though the reliability index are the same for the same structure. |
