摘要: 以 9 度區(qū)某體育館為例,對高烈度地區(qū)體育館建筑進行隔震設(shè)計研究. 通過對比減震方案和隔震方案,結(jié)果表明隔震方案減震效果更明顯,經(jīng)濟性更優(yōu). 對比了隔震層位于首層和基礎(chǔ)層的布置方案,結(jié)果表明隔震層位于首層承載力更好,經(jīng)濟性更優(yōu). 通過對比隔震前后結(jié)構(gòu)的地震響應(yīng),得到隔震層上部結(jié)構(gòu)最大水平減震系數(shù)為0. 33,隔震方案減震效果顯著. 罕遇地震彈塑性分析結(jié)果表明關(guān)鍵構(gòu)件均處于性能點 IO 之前,說明結(jié)構(gòu)具有較好的耗能作用,抗震設(shè)計達到性能 2 的設(shè)計要求. 對中震時程分析結(jié)果進行包絡(luò),分析結(jié)果表明設(shè)計截面配筋的承載力可以包絡(luò)中震時程分析構(gòu)件內(nèi)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.
