| 摘 要： | 用一次二阶矩法求工程结构的可靠度会产生误差 ,这误差产生的原因是将极限状态函数在验算点处的泰勒级数仅取线性部分来近似 ,本文用二阶方向导数分析这误差对工程的影响 .
|
| 关 键 词： | 一次二阶矩法 可靠度 误差 方向导数 |

| Abstract: | It can bring error to analyze the reliability of en gineering structure through a second order moment The reason that causes the error is that Taylor series of limit state function i n checking calculating point is approximate by choosing the linearity part. The authors analyzed the influence o f the error to engineer by second order directional derivation. |

| Keywords: | a second order moment reliability error directiona l derivation |
