| 摘 要： | 针对胶合木梁-柱节点抗弯能力弱的问题,提出了一种带隅撑的胶合木梁-双肢柱框架结构节点,以提高节点的转动刚度,改善梁柱结构框架的抗侧性能.对3组6个足尺胶合木梁-双肢柱框架结构节点进行了单调和低周反复加载试验以研究节点的抗震性能.结果表明:无隅撑节点类似于铰接,抗弯承载力很小,增设隅撑后显著提高了节点的转动刚度和抗弯承载...

| Abstract: | Aiming at the problem of weak bending resistance of glulam beam-to-column joints,a kind of glulam beam-to-battened column frame joint with knee brace was proposed to improve the rotational stiffness of joints and the lateral resistance of beam-to-column frames.Monotone and low cyclic loading tests were carried out on 3 groups of 6 full-scale glulam beam-to-battened column frame joints to study the seismic performance of the joints.The results show that the joint without knee brace is similar to the hinged joint,and the bending capacity is very small.The rotational stiffness and bending capacity of the joint with additional knee brace are significantly increased by 7.71 times and 6.80 times,respectively.The joint with knee brace has better energy dissipation and deformation capacity,the section size of knee brace has a significant effect on the rotation performance of the joint,the bending capacity of the joint with small section knee brace does not decrease much,but the ductility increases,the cumula‐tive energy consumption increases,and the failure starts from the knee brace,which can improve the seismic performance better.Finally,the optimization measures to improve the joint structure are proposed. |
