摘要
针对一种装配式钢筋混凝土盒式结构房屋 ,研究了其在各层之间均设置摩擦隔震部件时的地震反应分析模型和理论。在该体系中 ,除基础部位允许产生摩擦滑动外 ,上部各层也采用了摩擦滑动隔震构造 ,这种体系将房屋结构沿竖向在每层之间的隔震缝处断开 ,从而由下至上反复多次改变了地震作用的传播方式 ,并在地震反应分析中增加了较大难度。为此 ,合理建立了地震反应动力分析的结构模型 ,并重点对层间摩擦隔震的力学机制作了理论研究 ,建立了地震反应时程分析的有关公式 。
According to a fabricated reinforced concrete model building the analysis mode and theory of earthquake reaction are analyzed when the sliding isolation components are installed in several layers. In this system the foundation is permitted with sliding and upper layer adopts sliding isolation structure. This system changes the mode of transmission of earthquake reaction and adds more difficulties in the earthquake reaction analysis. Author establishes proper structural model of earthquake reaction dynamic analysis and studies mechanical mechanics. The corresponding formula of real time analysis for earthquake reaction is built to supply the foundation for dynamic calculation of this structure.
