转换大梁与剪力墙暗柱节点低周反复荷载试验

对上海浦东香格里拉大酒店扩建工程中的转换大梁与剪力墙暗柱节点的1/8比例模型进行低周反复荷载试验,研究该节点的破坏机理、受力和变形特点、暗柱上的轴压力大小和转换大梁的纵筋在节点内的锚固长度对节点受力性能的影响;检验原节点结构设计是否满足抗震要求;最后,根据模型试验的结果分析原型节点受力性能.

Low-cycle Test on Joint of Transfer Girder and Boundary Column of Shear Wall

The test was carried out on the 1/8 scale models of the joint of transfer girder and the boundary column of shear wall in the extension project of Shanghai Shangri la Hotel under cyclic loading. The damage mechanism, the characteristics of load and deformation, and the effect on the performance of the joint of the axial force exerted on the boundary column and the anchorage length of the longitudinal reinforcement of the transfer girder in the joint were studied. Then, the appraisement on whether the structural design of the prototype joint meets the seismic requirements was made. At last, based on the test results the performance of the prototype joint was analyzed.
