摘　　要：详细论述了山西高烈度区某幼儿园建筑采用隔震技术的分析方法及流程,采用隔震技术后延长了整个结构体系自振周期,降低了输入上部结构的水平地震作用,使得结构达到降低一度设防烈度的防震要求。从分析结果可知,在高烈度区学校、幼儿园多层建筑中采用隔震技术,可延长结构的自振周期达3~4倍,主体结构的地震作用可降低至原来的1/3~1/4,有效减轻上部结构在地震作用下的变形、损伤,可实现保护主体结构、非结构构件及装修、内部设施的安全。A kindergarten of Shanxi high earthquake intensity area that adopt the analysis method of isolation technology is presented.By the calculation,the whole structural system natural vibration period is extended,the input horizontal seismic action of upper structure is lowered,and the structure meets the requirements of reducing 1 degree fortification intensity. From the analysis results,by using the seismic isolation technology in the schools and kindergartens of high intensity region,the structural natural vibration period can be extended 3 to 4 times,the earthquake effect of the main structure can be reduced to 1/3 ~ 1/4 of the original,it can be effectively reduce the structural deformation and damage of the upper structure under the earthquake action,and protect the main structure,nonstructural unit,decorate and the internal facilities.
