摘　　要：对位于8度(0.30g)区重点设防类的医疗建筑,采用隔震技术进行设计,隔震支座由带有铅芯的橡胶支座和不带铅芯的橡胶支座组成,采用ETABS和ABAQUS两种有限元软件对结构进行弹性和弹塑性地震反应计算分析。分析结果表明:本工程隔震支座的设置满足规范要求的压应力、水平变形、竖向拉应力和抗风承载力等的相关要求;采用隔震技术可显著降低上部结构地震作用下的楼层剪力、层间位移;水平减震系数为0.336,上部结构的设计可按7度(0.15g)进行地震作用计算;在罕遇地震作用下,结构满足“大震不倒”及对医疗建筑更高的设防要求。The isolation technology is used to design the key fortified medical buildings located in the 8 degree(0.30g)area.The isolation bearing is composed of rubber bearing with lead core and rubber bearing without lead core.Two kinds of finite element software,ETABS and ABAQUS,are used to calculate and analyze the elastic and elastic-plastic seismic response of the structure.The analysis results show that the setting of isolation bearings in this project meets the relevant requirements of compression stress,horizontal deformation,vertical tensile stress and wind resistance bearing capacity required by the code;The use of isolation technology can significantly reduce the floor shear force and inter story displacement of the superstructure under seismic action;The horizontal damping coefficient is 0.336,and the design of superstructure can be calculated according to the seismic action of 7 degrees(0.15g);Under the action of rare earthquake,the structure meets the requirements of"No Collapsing in the Strong Earthquake"and higher fortification for medical buildings.
