为研究高层装配式混凝土结构框架梁柱节点的抗震性能,以某高度100 m的装配式混凝土框架-核心筒结构为原型,选取中间层(17层)和顶层(33层)典型的中间节点,设计足尺试件进行低周反复荷载试验,考察节点的刚度、承载力、开裂破坏形态、滞回特性、延性性能、耗能能力等指标,并研究了拼缝及梁钢筋锚固方式对梁柱节点抗震性能的影响。通过与现浇节点对比试验表明:梁纵筋在节点中采用贯通或有效锚固方式的抗震性能基本一致;现浇节点与装配式节点抗震性能基本一致,均表现为弯曲或弯剪复合破坏,节点区交叉裂缝明显;随轴压比减小,节点区梁端拼缝剪切变形增大,柱端、叠合梁拼缝变形不明显。 In order to study the seismic behavior of beam-column joints of high-rise prefabricated concrete structures, a typical intermediate node of the middle layer (17 layers) and the top layer (33 layers) was selected from a prefabricated concrete frame- Full-scale specimens were designed to carry out low-cycle cyclic loading test. The stiffness, load carrying capacity, cracking failure mode, hysteretic behavior, ductility and energy dissipation of the joints were investigated. The effects of patchwork and beam- Seismic behavior of joints. Compared with the cast-in-place test, it is shown that the seismic performance of the beam is consistent with that of the anchorage method. The seismic performance of the cast-in-situ joint is almost the same as that of the fabricated node, The cross cracks in the area are obvious. With the reduction of axial compression ratio, the shear deformation of beam-end patchwork joints in the node area increases, and the deformation of column-end and composite beam patchwork is insignificant.
