［摘要］針對云南省博物館新館的建筑特點(diǎn)，選取了合適的隔震支座，并對隔震支座進(jìn)行了合理的平面布置；利用SAP2000軟件對結(jié)構(gòu)進(jìn)行地震響應(yīng)分析，采用Bouce Wen模型模擬隔震支座；對比分析了多遇地震、設(shè)防地震及罕遇地震作用下隔震結(jié)構(gòu)和非隔震結(jié)構(gòu)的層間剪力、層間加速度及層間位移角。結(jié)果表明，隔震結(jié)構(gòu)的動(dòng)力特性優(yōu)于非隔震結(jié)構(gòu)，隔震結(jié)構(gòu)可以有效降低地震反應(yīng)。為驗(yàn)證數(shù)值分析的可靠性，采用1/30縮尺比例模型進(jìn)行模擬地震振動(dòng)臺(tái)試驗(yàn)，試驗(yàn)結(jié)果表明計(jì)算分析是可靠的。

Abstract:According to the architecture characteristics of New Yunnan Provincial Museum, the appropriate isolation bearings were selected and reasonable plane layout of isolation bearing was conducted. SAP2000 software was used to conduct seismic response analysis on the structure, and Bouce Wen model was adopted to simulate isolation bearing. Contrast analyses on the interlayer shear force, interlayer acceleration and interlayer displacement angle of isolation structure and non-isolation structure were conducted respectively under frequent earthquake, fortification earthquake and rare earthquake. The results show that the dynamic characteristics of isolation structure are better than that of non-isolation structure, and isolation structure can effectively reduce the seismic response. To verify the reliability of numerical analysis, simulated earthquake shaking table test was conducted on 1/30 scale model, and the test results show that the calculation and analysis are reliable.
Keywords:New Yunnan Provincial Museum; seismic isolation design; shaking table test; seismic response analysis
