摘要: 以 9 度区某体育馆为例,对高烈度地区体育馆建筑进行隔震设计研究. 通过对比减震方案和隔震方案,结果表明隔震方案减震效果更明显,经济性更优. 对比了隔震层位于首层和基础层的布置方案,结果表明隔震层位于首层承载力更好,经济性更优. 通过对比隔震前后结构的地震响应,得到隔震层上部结构最大水平减震系数为0. 33,隔震方案减震效果显著. 罕遇地震弹塑性分析结果表明关键构件均处于性能点 IO 之前,说明结构具有较好的耗能作用,抗震设计达到性能 2 的设计要求. 对中震时程分析结果进行包络,分析结果表明设计截面配筋的承载力可以包络中震时程分析构件内力.

Abstract:Taking a gymnasium in a 9 degree area as an example, the isolation design of a gymnasium building in highintensity area was studied. By comparing the damping scheme and the isolation scheme, the results show that the isolationscheme has more obvious damping effect and better economy. The layout schemes of the isolation layer located on the firstlayer and the foundation layer were compared. The results show that the isolation layer in the first floor has better bearingcapacity and better economy. By comparing the seismic response of the structure before and after the isolation, themaximum horizontal damping coefficient of the upper structure of the isolation layer is 0. 33, and the isolation scheme has aremarkable damping effect. The elastic-plastic analysis results of rare earthquakes show that the key components are allbefore the performance point IO, indicating that the structure has good energy dissipation and the seismic design meets thedesign requirements of performance 2. Envelope the results of time history analysis of moderate earthquakes. The analysisresults show that the bearing capacity of the design section reinforcement can contain the internal force of the componentunder time history analysis of moderate earthquake.
