隔板贯通式钢框架梁柱节点试验研究
|
摘要
为了验证截面小而柱壁厚的隔板贯通式梁柱节点的破坏特征及力学性能,对1个T字形足尺隔板贯通式梁柱节点进行低周期反复荷载作用的试验.分析了试件的破坏过程及特征,并对节点的承载力及延性等性能进行了研究.试验结果表明:这种节点破坏时梁端形成塑性铰,满足"强柱弱梁、强节点弱构件"的设计要求;节点的滞回曲线饱满,表明其较好的耗能能力及较高的承载力.
In order to verify the failure modes and mechanical properties of the joint of column and beam which section is small and wall of column is thickness with perforation type diaphragm,an experiment was done under the condition of low cycle frequency load to a perforation type column and beam joint with full-size T-shaped diaphragm.The failure process and feature of specimen were analyzed;carrying capacity,ductility and more performance were studied.Experimental results show that the specimens formed plastic hinges at the end of beam when joint is in failure;it meets the design requirement of strong column to weak beam and strong node to weak component.The hysteresis curve of the joints is full;it shows better carrying capacity and energy dissipation capacity.
