摘　　要：某49层高层建筑结构形式为带转换层的部分框支剪力墙结构,采用主次梁转换,其多项指标超限使该结构属于特别复杂高层建筑结构。为检验其抗震性能,采用1;20的比例制作了缩尺模型,并进行了振动台试验,模型总重量达到59.9 t,加速度相似比降至1.69。本文研究了模型结构的动力特性、地震反应特征、破坏形态和破坏机理。并且应用有限元程序软件对结构的抗震性能进行了深入的研究,试验与计算结果符合较好。The partial frame-supported shear wall structural system is applied to a 49-storey high-rise building. As a complex girder transfer strueture is adopted and several structural indexes exceed the limitation of current design codes, the building belongs to special complex high-rise building. In order to investigate the aseismic performance of this structure, a 1 ： 20 scale model is fabricated and tested on the large-scale shaking-table. The total weight of the model is 59. 9 t, which makes the similarity radio of acceleration descended to 1.69. Based on the test, the dynamic properties, seismic responses ,failure model and mechanism are discussed. Moreover, the seismic responses of the model are analyzed by finite element analysis program. The analysis results have a good agreement with the test results.
