| 摘要: |
| 该方法将传递函数方法与传统的随机摄动分析理论相结合，将随机场作Karhunen-Loeve正交展开，对静态随机梁结构进行了分析，并计算了其可靠性指标。这样一来克服了传统的有限元数值方法计算量大的困难，确立了随机梁结构分析的一种解析方法。 |

| Abstract: |
| The transfer function method is combined with the traditional spectral approach theory. The stochastic field is expanded by orthonormal Karhunen-Loeve method, the static stochastic beam analyzed and its credibility reckoned in the end. This method conquer the difficulty of the huge numerical computation of the traditional finite element method and an analytical analysis method of stochastic structure analysis is formed. |
| Keywords: stochastic structures transfer function spectral approach theory credibility |
