摘　　要：为研究厚板转换全框支剪力墙结构的整体抗震性能,并检验该结构转换厚板的有效性,在重庆大学土木工程学院振动台实验室开展了缩尺模型结构的模拟地震振动台试验,试验对象为某36层车辆段上盖建筑。本文阐述了厚板转换全框支剪力墙结构振动台试验中模型的设计过程;介绍了测点布置与加载方案;对比分析了不同抽层简化方案对结构的影响。研究结果表明,对于厚板转换全框支剪力墙结构,抽层后依据刚度与强度等效原则调整构件截面能有效降低简化模型与原型的误差;抽层起始位置应被保证距离试验重点研究楼层不低于3层;连续抽层层数为1层时误差最小,建议选择连续抽层层数为1层。In order to study the seismic performance of the fully frame-supported shear wall structure with thick transfer plate and to test the effectiveness of the thick transfer plate of this structure,the shaking table test of the reduced scale model structure was conducted in the shaking table laboratory of the School of Civil Engineering,Chongqing University.The test object is a 36-story vehicular rail superstructure.This paper describes the model design for the shaking table test of the fully frame-supported shear wall structure with thick transfer plate.The arrangement of measurement points and the loading scheme are also introduced.The effects of different story slab elimination schemes on the structure were compared.For fully frame-supported shear wall structure with thick transfer plate,the results show that adjusting the section of the member according to the principle of stiffness and strength equivalence after story slab elimination can effectively reduce the error between the simplified model and the prototype;the starting position of extraction should be guaranteed to be no less than 3 stories from the test focus stories;the error is minimized when the number of story slab elimination stories is 1.It is recommended that the number of story slab elimination stories is 1.
