土-结构相互作用对层间隔震结构的影响分析
|
摘要
基于集总参数SR(Sway-Rocking)模型,建立层间隔震结构考虑土-结构相互作用的简化分析模型,推导得到简化模型动力特性参数表达式,进而通过对结构反应传递函数和方差进行分析,讨论波速参数和结构高宽比对体系反应的影响。结果表明,考虑SSI效应的层间隔震结构,延长了体系周期,同时,也放大了各子结构位移反应,而对上、下部子结构的加速度反应影响不同,其影响程度主要与场地剪切波速和体系高宽比有关。
A simplified analysis model of inter-story isolation structure considering soil-structure interaction(SSI) is proposed based on an SR(sway-rocking) model. Analytic expressions for dynamic characteristic parameters are derived, and then the influence of wave parameters and height to width ration on structure response through the structure transfer function and variance are discussed. The results show that considering the SSI of the Inter-story isolation structure which period are prolonged and also substructure displacement are enlarged. But to substructures acceleration response is different, it is mainly related to site shear velocity and structure height to width ration.
