【摘要】 采用ANSYS有限元分析软件,通过对混凝土框架结构是否采用隔震技术进行对比分析,研究隔震结构在不同烈度、不同场地条件地震作用下的动力响应,分析了加速度、位移、层间位移的变化规律,研究表明:与传统抗震结构相比,采用滑移隔震结构的上部结构的加速度反应明显减小,隔震结构层间位移很小,纯摩擦滑移隔震结构的残余位移是不可忽略的,可为滑移隔震研究提供参考。更多还原

【Abstract】 Through comparing and analyzing whether or not the isolation technique is used for concrete frame structures by using ANASYS,the dynamic responses of the isolation structure in different field conditions and seismic intensities are studied,and the variation laws of the acceleration,displacement and interlayer displacement are analyzed.The study results show that comparing with the results of traditional seismic structures,the acceleration in the upper structure used with the sliding isolation structure is decreased obviously,the interlayer displacement is a little,and the pure friction as well as its residual displacement could not be neglected.All these as mentioned above could provide references for the research of the sliding isolation.更多还原
