| 摘 要： | 梁的随机分析是结构随机分析的重要基础之一，尤其是作为精确解的显式解析争更不易获得，目前尚未见到有关载荷随机时梁的随机分析的报道，本文首次给出了梁载荷随机时计算位移统计矩的解析法和数值法，最后通过算例验证了本文所提出的方法的正确性。

| Abstract: | Stochastic analysis of a beam was one of the important bases of structural stochastic analysis, an explicit analytic solution served as an exact solution was especially difficult to obtain There has been no paper availabel for stochastic analysis of a beam under random load up till now,Based on the deflection curve of a beam with random stiffness, and analytic expressionsand a numerical method are given in this paper.The validity of the solution is verified by an example. |

| Keywords: | stochastic finite element random field local average method |
