| 摘 要： | 对结构随机响应分析的数值积分方法进行了深入的研究。首先，直接从控制方程出发计算加速度，其次，给出了位移和速度的一种近似计算公式，最后，推导出响应均方值的离散计算表达式。就两个算例进行了数值仿真，结果表明该方法对于结构的随机响应分析是有效的。

| Abstract: | In this paper, a numerical method for structure stochastic response analysis is presented. The acceleration is first evaluated from governing equation, secondly, the formulae of displacement and velocity are developed basing on some assumptions, and then the discrete expressions of the response mean square value are deduced. Two numerical examples are performed, which results show that this method is effective for the stochastic response analysis. |
