摘要
设计了一种碟形弹簧竖向减震装置,进行了力学性能试验,并对其竖向地震响应进行了时程动力分析,对比了隔震结构及其相应非隔震结构的动力特性,计算了罕遇地震作用下结构的最大层间轴力、加速度、位移等,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.
A Vertical seismic isolation system using disk spring is designed. The experiment is conducted in dynamic character and it is analyzed using the timehistory analysis method. The maximum acceleration and the displacement response between story and story are provided. The differences between the isolated building and the non -isolated building are discussed. It is proven that the disk spring device can work efficiently in vertical seismic isolation.
