活性粉末混凝土是一种具有超高强度、高耐久性和高韧性的超高性能水泥基材料，尤其适合用于框架结构中主要抗震构件。采用基于OpenSees的有限元非线性节点模型，对活性粉末混凝土梁柱节点进行了拟静力加载模拟，研究了不同轴压比下梁柱节点的抗震性能，得出了其滞回曲线和骨架曲线。结果表明：活性粉末混凝土梁柱节点具有良好的承载力和抗震性能，强度、刚度退化缓慢，延性较好。

Reactive powder concrete reactive pocoder concrete is a new cementitious material with high strength ,durability and tough-ness.It is especially suitable for main seismic components of a RC frame.It takes a nonlinear model for beam-column joint based on OpenSees.Simulation on reactive pocoder concrete beam-column joint under reversed cyclic loading with different axial compression ratio was carried out.The hysteretic curve and skeleton curve are obtained.According to the results ,the reactive pocoder concrete beam-column joint has better bearing capacity and seismic performance.The strength and stiffness degradation is not obvious ,the ductility is better.
