| 摘 要： | 对高宽比为5的钢框架隔震结构模型,采用不同的地震波进行了水平向和竖向双向地震输入的振动台试验,利用时程分析法完成了模型结构地震反应的数值分析．结果表明,大高宽比隔震结构在水平向和竖向双向输入情况下的减震效果良好．在8度和9度地震作用下,试验观测到隔震层竖向进入了非线性受拉状态,测得支座最大拉应力3．176 MPa,隔震结构未出现倾覆．试验还发现,竖向输入地震动对隔震结构水平向地震反应的影响很小．对高宽比小于5的隔震结构进行水平向地震反应分析时,可忽略竖向地震对结构反应的影响．

| Abstract: | The shaking table tests are completed on a steel frame model with aspect ratio of 5 with horizontal and vertical earthquake input of different earthquake waves in this paper,and the numercial analysis of earth- quake response to model structure is also performed by time history analysis method.The experiment results show that the large aspect ratio isolated structure has good isolation effect under the earthquake in two direc- tions.Under the action of strong earthquake waves,we found that the isolation lay... |
