空间相关地面运动下结构的随机反应分析

Stochastic Response Analysis of Structures underSpace-interrelated Ground Motion Model

本文对文献［１］的空间相关地震模型进行了分析，并推导了在这个模型下多支撑结构随机反应分析的公式．本文对一单跨拱式结构进行的分析反映了对支度差动很敏感的超静定结构在空间相关地面运动下反应的一些特点。

This paper analyses the space-intenttelated earthquake model given in leference[1], anddeduas the stochastic response formulas of structres under this model. This paper alsorepresents some response characteristics of the statically indeterminate structures which aresensitive to the difference of support inchons by analysing a single-span arch struture,under the space-interrelated ground motion model.
