摘要
提出一种新型装配整体式柱与柱节点连接方式——局部外包钢管柱接头。通过四个足尺试件在水平低周反复荷载下的对比试验,研究其破坏形态、滞回曲线和骨架曲线等。试验结果表明:采用局部外包钢管装配整体式柱子接头整体性能较好,没有出现拉拔脱离现象;节点滞回曲线和骨架曲线与相同条件下的现浇混凝土柱相近,具有良好的延性和耗能能力;试件破坏为延性较好的大偏心受压破坏。研究结果能够为装配整体式柱连接的理论研究和实际工程应用提供参考。
A new assembled monolithic column joints were put forwords： local outsourcing steel tube column joints. Through four full-scale specimens under cyclic loading contrast test, the failure form, hysteresis curve and skeleton curve were studied. The test results show that： the overall performance of outsourcing steel tuble column joint is better than other tradition joints, for without drawing or detachment phenomenon; Under the same condi- tions, node hysteresis curve and skeleton curve are similar to cast-in-site RC columns. These joints also have good ductility and energy dissipation capacity, rupture of the test＇ s samples belong to Large eccentric compression fail- ure, which ductility is better. The research results can provide the reference of theory research and practical engi- neering application connected to the assembled monolithic column.
