摘　　要：通过对附加阻尼器的预应力装配式框架结构节点和现浇框架节点的低周反复荷载试验,研究了钢筋混凝土框架结构和附加阻尼器的预应力装配式框架结构节点的裂缝分布、破坏形态、滞回曲线及位移延性等抗震性能。试验结果表明:附加阻尼器的预应力装配式框架结构抗震性能良好,在抗震设防地区具有良好的应用前景。Through the experiment under low cyclic loading of cast-in-situ reinforced concrete frame beam- column joints and damped beam-column joints of prestressed concrete frame structures, the seismic performance including crack distribution, failure pattern, hysteresis curve, and the displacement ductility are analyzed. The results showed that： assembled prestressed concrete frame structure with damped beam-column joints have good seismic performance, and have wide application prospect in earthquake area.
