摘　　要：本文进行了四个部分预应力混凝土扁梁框架节点的拟静力试验研究。通过四个不同试件的试验研究分析了节点的变形能力、耗能能力、延性和刚度退化等抗震性能,同时分析了低周反复荷载作用下预应力混凝土框架节点的破坏机理。Four beam-column joints with partially prestressed concrete flat beam are tested under reversed cyclic lateral loading in this paper. The aseismatic behaviors of beam-column joints such as transform capacity, energy dissipating capacity, ductility and stiffness deterioration etc. are studied. Based on the results of the four-joint tests,the failure mechanism of the beam-column joints of frame under reversed cyclic load is analysed.
