传统风格建筑结构关键节点设计和试验
发布时间：2018-10-11 14:43
【摘要】：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。
[Abstract]:The performance of key joints in traditional architectural structures is very important to the performance of the structure. Two groups of joint tests are carried out to distinguish and consider the effects of the bucket arch members on the performance of the joints, and there are 2 specimens in each group of tests. The axial compression ratio is 0.3 and 0.6 respectively. The test results show that the failure of bucket arch joint (ZL1 series) is mainly concentrated in the weld zone between upper and lower columns, while the damage of bucket arch action joint (YL1 series) is mainly concentrated in the coggygriated coggygrium joint and the short column area of the joint. The joint of ZL1 series is lower than that of YL1 series, and the stiffness and strength degradation is slower. On the basis of this, the engineering design suggestions and strengthening measures are given.
