随机时变荷载作用下结构高维时变超越率分析

Multi Dimension Time Dependent Crossing Rate Analysis of Structures under the Effect of Random Time Dependent Loads

本文根据高维向量随机过程的首次超越率理论，提出了工程结构在高维随机时变荷载作用下的时变超越率计算方法，以及推广的ｎ维状态空间ＲｉＣｅ公式。

In this paper the time dependent crossing rate computing method and the generalization Rice formula of n demension of structure,effected under random time dependent loads,are proposed based on multi demension stochestical process vector theory.
