摘　　要：通过对不同预压应力下附加阻尼器的预应力装配式混凝土框架结构中节点试验研究和现浇钢筋混凝土框架结构中节点的低周反复荷载试验,研究了不同预压应力下附加阻尼器的预应力装配框架中节点和现浇钢筋混凝土框架结构中节点的裂缝发展、破坏形态、滞回曲线、骨架曲线、刚度退化曲线及能量耗散与延性等抗震性能指标。试验表明:附加阻尼器的预应力装配框架节点具有良好的抗震性能,提高预压应力在一定程度上可以提高装配节点的抗震性能。Through low cyclic loading tests on prestressed assembling frame midside nodes with additional dampers under different prestressing forces and cast-in-situ reinforced concrete frame midside nodes, the prestressed assembling frame midside nodes with additional dampers under different prestressing forces were studied. Cast-in-place reinforced concrete structure node＇s cracks,failures,bysteretic curves,skeleton curves, stiffness degradation and energy dissipation seismic performance index curve and ductility were discussed. Tests show that the prestressed assembling frame nodes with additional dampers have good anti-seismic performances, enhancing compressive prestress to a certain extent and improving seismic behaviors of assembling nodes.
