摘　　要：对河北理工大学研制的由碟形弹簧和粘弹性阻尼器组合而成的碟形弹簧竖向减震装置进行了力学性能试验研究,建立了恢复力模型。并以一个8层框架为例,对其竖向地震响应进行了时程反应分析,对比了隔震结构及其相应非隔震结构的动力特性,计算出罕遇地震作用下结构各层的最大加速度和位移。结果表明,该竖向减震装置能够起到有效减轻竖向地震动的作用。The mechanical property test study on vertical seismic isolation system which by made up with disk spring and viscoelastic damper has been done by Hebei Polytechnic University. The resilience model was built up. And the vertical seismic response of eight- story frame is analyzed using time-history analysis method. The differences between the isolated building and the non-iselatod building are discussed. The maxima of the acceleration and the displacement response between story and story are provided. It is approved that the device of disk spring can work efficiently in seismic isolation.
