钢管混凝土柱-钢筋混凝土环扁梁节点性能试验研究
|
摘要
本文进行了钢管混凝土柱-钢筋混凝土环扁梁节点的静载和低周反复荷载试验,分析了节点的破坏形态、承载能力、延性、耗能能力等性能。本次试验结果显示,钢管混凝土核心区未发生屈服破坏情况,塑性铰产生于扁梁和环扁梁交界处(静载)和环扁梁上(低周反复荷载),环扁梁与钢管混凝土柱间未发生明显滑移现象;试验节点连接可靠,具有较好的承载力、延性以及耗能能力,能够满足延性抗震设计要求。
On the basis of the experiments of concrete filled steel tubular column(CFTC)-reinforced concrete ring flat beam joints under static loading and quasi-static cyclic loading,the failure pattern,loading capacity,ductility and energy-dissipating capacity of the joints were analyzed.The test results reveal that the joint core of CFTCs is integral,and the plastic hinges appear at the interface between ring flat beams and flat beams(static loading) or ring flat beams(quasi-static cyclic loading),and the slippage between ring flat beams and CFTCs can be ignored.This kind of joints has better loading capacity,ductility and energy-dissipating capacity,and can meet the requirements of ductile seismic resistant design.
