摘　　要：为获取馆藏文物震害数据并开展文物防震保护研究,设计了一个3层单跨钢框架结构模型用于振动台试验。选择8度小震、中震和大震地震动,分别进行单向、双向和三向地震动试验,分析了不同地面材质对浮放展柜和隔震展柜以及展柜内浮放文物地震反应的影响。基于试验对象和试验目的,从振动台试验方案设计的角度探讨了结构模型设计、展柜布置、文物选择与布置、传感器选型与布设、地震波加载工况等因素对试验效果的影响。该试验方案设计为顺利完成馆舍-展柜-文物体系的振动台试验提供了保障,设计中的经验与教训可为以后开展类似的大型振动台试验提供借鉴。初步分析试验结果显示,浮放展柜在水平单向地震动激励下的运动状态不仅局限于水平运动,相同高宽比的不规则文物与规则木块之间的运动状态存在显著差异。To obtain seismic damage data for museum collections and conduct research on seismic protection of cultural relics,a three-story single-span steel frame structure model was designed for shaking table tests.Earthquake motions corresponding to low,medium,and high levels of intensity(8-degree scale)were selected,and unidirectional,bidirectional,and triaxial shaking table tests were carried out to analyze the effects of different ground materials on the seismic responses of both floating cabinets and base-isolated cabinets,as well as the cultural relics placed within them.Based on the characteristics of the test objects and objectives,factors such as structural model design,cabinet arrangement,selection and placement of relics,sensor selection and layout,and earthquake wave loading conditions were discussed from the perspective of shaking table test scheme design and their impact on the test outcomes.This experimental design ensures the successful completion of shaking table tests for the museum-building-cabinet-relic system,and the experiences and lessons learned from the design can provide valuable references for future large-scale shaking table tests.Preliminary analysis of the test results indicates that the motion state of the floating cabinets under horizontal unidirectional seismic excitation is not limited to horizontal movement,and there are significant differences in the motion states between irregular relics and regular wooden blocks of the same height-to-width ratio.
