In order to conduct research on the dynamic properties of frame joints with post-installed chemically rebar, five RC members are tested under cyclic load and constant axial, in which four of them are post-installed chemically bonded longitudinal rebar, and compares the results with one cast-in-place member. Under low frequency cyclic loading, test procedures are described, experimental data are analyzed and compared, and the effects of the embedded depth and the rebar diameter on the seismic behavior are studied. Results show that the seismic behavior can be improved for RC structure with increasing of the bond strength, including the ductility, energy dissipation, and the bearing capacity. But the embedded depth must be increased when the diameter of the rebar was raised. The research process is similar to the work during construction, so the result of the research is credible, and can be referenced during design for strengthening concrete structure.%为了研究植筋钢筋混凝土锚固构件的抗震特性,对5个构件进行了低周反复加载试验,其中1个整体浇注构件,4个植筋构件,钢筋直径分别为20和25 mm的植筋构件在不同锚固深度(15D和20D)下各1个.试验研究了植入钢筋深度及钢筋直径变化对节点抗震性能的影响.结果表明:随着锚固深度的增加,植筋构件的极限承载能力、延性及耗能能力均有所提高;当钢筋直径增加后,为避免脆性破坏,应适当增加锚固深度.本试验模拟实际工程中植筋的工艺流程及环境,选用了常用植筋直径,试验结果将为混凝土结构植筋加固设计提供依据.
