[摘要]针对云南省博物馆新馆的建筑特点,选取了合适的隔震支座,并对隔震支座进行了合理的平面布置;利用SAP2000软件对结构进行地震响应分析,采用Bouce Wen模型模拟隔震支座;对比分析了多遇地震、设防地震及罕遇地震作用下隔震结构和非隔震结构的层间剪力、层间加速度及层间位移角。结果表明,隔震结构的动力特性优于非隔震结构,隔震结构可以有效降低地震反应。为验证数值分析的可靠性,采用1/30缩尺比例模型进行模拟地震振动台试验,试验结果表明计算分析是可靠的。

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
