| 摘 要： | 为研究型钢混凝土(SRC)异形柱框架节点的破坏特征和抗震性能,进行了9个中间层边节点、4个角节点和4个中节点的低周反复荷载试验。观察了各类型节点的受力过程及破坏形态,并分析了试件的荷载-位移滞回曲线、承载能力、层间位移角和延性以及耗能能力等力学特性。结果表明:SRC异形柱框架节点的典型破坏形态是节点核心区剪切斜压破坏和梁端弯剪破坏;滞回曲线饱满,层间位移角延性系数及位移延性系数介于1.80~5.63,弹塑性极限层间位移角约为1/67~1/28,等效粘滞阻尼系数介于0.150~0.294,破坏时节点核心区的剪切角约为0.03~0.04。并给出了节点设计建议。

| Abstract: | In order to investigate the failure modes and seismic behavior of steel reinforced concrete(SRC) special-shaped column-beam joints,17 specimens were tested under reversed cyclic loading.The failure process and patterns were obtained.The failure characteristics,mechanical behaviors such as the load-displacement hysteresis loops,load carrying capacity,interstory drift ratio,ductility and energy dissipation of the joints were analyzed.It is shown that the main failures patterns of the column-beam joints are th... |
