摘　　要：以高烈度区某小学框架结构教学楼为例,通过隔震设计在建筑隔震层设置不同型号的橡胶支座实现建筑隔震。采用YJK软件建立了隔震与非隔震结构计算模型,并基于时程分析法对其进行了地震响应分析,提出了相关的隔震构造措施。结果表明,在进行隔震设计后,隔震结构与非隔震结构相比,其自振周期增大、层间剪力减小。罕遇地震作用下隔震支座最大拉应力、位移均能满足相关规范要求。Taking a primary school frame structure teaching building in a high intensity seismic zone as an example,this study achieves building isolation through setting different types of rubber bearings in the building isolation layer by isolation design.The isolation and non-isolation structure calculation models were established using YJK software,and the seismic response analysis was carried out based on the time-history analysis method.Relevant isolation structural measures have been proposed.The results show that after isolation design,compared with non-isolation structure,the isolation structure has a longer natural vibration period and smaller inter-story shear.Under the action of rare earthquakes,the maximum tensile stress and displacement of the isolation bearings can meet the relevant specification requirements.
