传统风格建筑结构中关键节点的性能对结构性能的影响至关重要,分别进行了2组节点试验,区分考虑斗拱构件对节点性能的影响,且每组试验有2个试件,轴压比分别为0.3和0.6。试验结果表明:未考虑斗拱作用节点(ZL1系列)的破坏主要集中于上下柱交接焊缝区域,而考虑斗拱作用节点(YL1系列)的破坏主要集中于上下柱栌斗处和节点短柱区域,且栌斗部位破坏较早,变形较大;ZL1系列试件相比YL1系列试件节点承载力低,刚度与强度退化慢;在此基础上给出工程设计建议和加强构造措施。
The influence of the performance of key nodes in the traditional building structure is crucial to the structural performance. Two sets of joint tests were conducted separately, and the impact of the arches on the performance of the joint was taken into consideration. There were two test pieces in each set and the axial pressure ratio was 0.3 and 0.6. The test results show that the damage of the joints (ZL1 series) without considering the brackets is mainly concentrated in the weld zone of the upper and lower columns, while the damage of the brackets (YL1 series) is mainly concentrated on the upper and lower columns, the joints and the short columns. In addition, the failure of the bucket part is earlier and the deformation is larger; the bearing capacity of the ZL1 series specimens is lower than that of the YL1 series specimens, and the stiffness and strength degradation are slow; on this basis, the engineering design suggestions and the strengthening of construction measures are given.
