【摘要】 为了研究钢骨高强混凝土框架节点的抗震性能,对五个钢骨高强混凝土框架节点进行了低周反复荷载作用下受力性能的试验研究.在试验研究基础上,考虑了节点配箍率、含钢率和轴压比,对节点延性、耗能和强度、刚度退化等影响,建立了钢骨高强混凝土框架节点的恢复力模型.

【Abstract】 In order to investigate seismic performance of joints in steel reinforced high strength concrete,the experiments were conducted on 1/2 scale specimens of frame joint in steel high concrete frames subjected to low-frequency cyclic loading.Based on the test results and analysis,force restoration model of this kind of Joints is established with consideration of the degree of joint ductility,capacity of energy dissipation,deterioration of stiffness by the stirrup ratio,steel ratio and axial compression ratio.
