为解决目前大跨空间结构隔震中存在的问题,本文介绍了一种新型的三维复合隔震支座,并将它应用于某一单层球面网壳结构中.根据支座的隔震目标设计了40种不同类型的支座进行参数分析.结构分析采用时程分析法,通过改变地震动的强度,全面研究了该三维复合隔震支座水平刚度及竖向刚度变化对网壳结构周期、杆件轴力及节点加速度的影响,并总结了不同工况下的变化规律.结果可为该支座在网壳中的参数选择提供参考,对推动该支座在实际工程中的应用具有积极意义.

A 3-dimensional seismic isolation bearing (3DSIB) was introduced first. In order to promote its practical application, parameter analysis was studied by applying it in a single-layer spherical lattice shell. Forty kinds of bearings were designed according to the seismic isolation targets. Time history analysis was performed to the structure. By changing the intensity of earthquake motion, the influence of horizontal and vertical stiffness of 3DSIB on periods, member axial force and nodal acceleration was analyzed comprehensively. The variation rules of seismic responses under different conditions were summarized. The results would provide references for parameter selecting of the bearing in lattice shells.
