摘　　要：研究隔震支座对多高层框架结构减震效果的影响,框架结构在隔震支座不同布置方案下的不同动力反应,寻找更优的隔震支座布置思路达到隔震支座更充分的使用。以5层、10层和15层的框架结构为研究模型,使用YJK软件对多遇地震下对结构在4种不同隔震支座布置进行时程分析。结果显示,在多层建筑中采用隔震技术的效果比高层建筑更为明显;多层建筑中将铅芯橡胶支座布置在基础的外围能更好减少建筑的层间位移,吸收更多的地震能量。Study isolation bearing of high-rise frame structure damping effect, the influence of vibration isolation bearing frame structure in different dynamic response under different layout plan, looking for a better vibration isolation bearing vibration isolation bearing arrangement of ideas to use more fully. Taking the frame structure of 5, 10 and 15 layers as the research model, YJK was used to analyze the time history of the structure layout in four different isolation bearings under multiple earthquakes. Results show that the effect of isolation technology are used in multi-storey building more clearly than high-rise buildings, multi-story buildings will lead rubber bearing to decorate the outside of the foundation can better reduce the displacement between layers architecture, absorb more seismic energy.
