中文摘要：
通过对9个型钢混凝土（SRC）异形柱框架边节点进行低周反复加载试验,观察了不同配钢形式、不同轴压比条件下SRC异形柱框架边节点的受力过程及破坏形态,得出了SRC异形柱框架边节点的荷载-位移滞回曲线和骨架曲线.根据试验结果,分析了节点承载力、延性、耗能以及刚度退化等性能.研究表明,SRC异形柱框架边节点的滞回曲线比较饱满,承载力高,耗能能力强,位移延性系数平均值可达到3.60,具有较好的抗震性能.
英文摘要：
According to the experimental study on 9 specimens of steel reinforced concrete（SRC） T-shaped column-beam joints under low cyclic reversed loading,the influence of the steel layout and the axial compression ratio on the failure process and patterns were analyzed,and the load-displacement hysteretic loops and skeleton curves are obtained.Based on the experimental results,the mechanical properties of the joints such as the load bearing capacity,ductility,energy dissipation,and the stiffness degeneration are studied.It is shown that the hysteretic hoops of the steel reinforced concrete T-shaped column-beam joints are plump.The joints have high bearing capacity,good ductility and energy dissipation capacity,which perform excellent seismic behaviors.
