Probability density evolution method for the analysis of linear stochastic structural static response under random loading is proposed.
提出了随机荷载作用下随机结构线性静力反应的概率密度演化方法。
The formulations of the structural static response, dynamic characteristics and dynamic response based on sensitivity analysis are also deduced in this paper.
同时推导出了结构的静力响应、动态特性、动力响应的灵敏度计算公式；
Different from the problem on static intensity, the relation between structural dynamic response and design variables is even more complex, and is high nonlinear.
与结构静态强度问题不同，结构动态响应与设计变量的关系更为复杂，是高度非线性的。
When linear structural systems involve parameter and load uncertainties, its static response will become uncertain.
如果结构系统的参数和载荷是不确定的，则结构系统的静态和动态响应也将是不确定的。
