以某钢筋混凝土多层框架结构教学楼工程为例，采用有限元软件SAP2000，对隔震结构和非隔震结构进行模态和时程分析，并对两种结构的分析结果进行了对比，结果表明，结构布置隔震支座后，可以有效延长结构自振周期，减小层间剪力和位移。%Taking the teaching building engineering with steel reinforced concrete multi-layer framwork structure as an example,the mode and time-history analysis were carried out for isolated and non-isolated structures based on SAP2000. Through the comparative analysis about the re-sults of the two structures,the results show that:when the structure was arranged isolation bearings,the structure natural vibration periods was ef-fectively extended,the interlayer shear force and displacement were decreased.
