摘　　要：通过对不同配筋率下现浇钢筋混凝土中框架节点和附加角钢板的预应力装配式混凝土中框架节点的低周反复荷载试验,研究了不同配筋率下现浇钢筋混凝土中框架节点和附加角钢板的新型预应力装配中框架节点的裂缝发展、破坏形态、滞回曲线、骨架曲线和刚度退化曲线等抗震性能指标。结果表明:附加角钢板的新型预应力装配式中框架节点具有良好的抗震性能,提高配筋率在一定程度上可以提高节点的抗震性能。Based on the low cyclic loading tests under different ratio of reinforcement of cast-in-place reinforced concrete frame joints and additional angle steel prestressed fabricated concrete frame joints, effects of different rein- forcement ratios of cast-in-place reinforced concrete frame joints and additional angle plate model prestressed assembling frame node crack developing, failure pattern, hysteresis curves, skeleton curves and the stiffness degradation curves of seismic performance index. The results show that ： the model of prestressed fabricated frame node additional angle steel plate has good anti-seismic performance, enhaning the ratio of reinforcement in a certain extent can improve the seismic behavior of the joints.
