In this paper, a method USES to calculate structure dynamic response is proposed, which is based on the three parameter reliability model and perturbation probabilistic finite element method.

将可靠性分析三参数法与摄动概率有限元法相结合，提出了一套求解结构体动态响应概率分布的方法。

Dynamic response analysis of tensioned cable and membrane structure is one of difficulties of structure design because of its tensioned-only, large deformation and small strain property.

由于膜材只能受拉不能受压以及大变形小应变的特点，其设计中动力响应分析是难点之一。
