方钢管混凝土柱-H型钢梁组合节点抗震性能试验

摘要
目的研究不同参数下的隔板贯穿式方钢管混凝土柱-H型钢梁组合节点的抗震性能.方法对2组共6个隔板贯穿式方钢管混凝土柱-H型钢梁足尺节点试件进行低周往复荷载试验,并且完成节点的非线性有限元分析,明确各试件的破坏过程及特征,并对节点的承载力、延性、耗能能力和刚度退化等抗震性能指标进行分析.结果隔板贯通节点滞回曲线饱满,具有较强的耗能能力,同时从强度和刚度退化曲线中可以观察到退化现象,并且满足"强柱弱梁,强节点,弱杆件"的设计原则.结论改变贯穿隔板的厚度对节点的抗震性能、延性性能以及刚度和强度退化影响不是很明显,但是随着隔板厚度的增加节点的抗震性能逐渐增强;改变贯穿隔板的外伸长度对节点的抗震性能有一定的影响.
The seismic performance for the joint of diaphragm-through-type concrete-filled square steel tube(DCFSST)column and H-shaped steel beam under the different parameters is researched in the paper.A low cyclic loading test for a group of 6 joints of the DCFSST column and H-shaped steel beam is carried on,and a nonlinear finite element analysis(FEA)is meanwhile performed,in order to develop the destruction process and characteristics of each specimen,and also to take an in-depth research and analysis on the joint bearing capacity,ductility,energy dissipation capacity and stiffness degradation.The research results show that this kind of the diaphragm-through-type joint has full hysteresis curves and strong energy dissipation capacity.From the curves of strength and stiffness degradation,the degradation phenomenon can be found,the requirement of the design principle of "strong column and weak beam,strong node and weak link" are met.Changing the thickness of the diaphragm does not obviously influence the seismic behavior,ductility performance as well as stiffness and strength degradation.However,increasing the diaphragm thickness of the joint can gradually enhance the seismic performance of the joints.Changing the overhang length of the diaphragm will have a certain influence on for the seismic performance.
