装配整体式浆锚插筋及钢板箍连接柱试验研究
|
摘要
为了研究装配整体式浆锚插筋及钢板箍连接柱的抗震性能,设计2根装配式连接柱与2根现浇柱足尺模型并进行了低周反复试验,对装配式连接柱与现浇柱的破坏机理、破坏形态、滞回曲线、骨架曲线、变形、耗能能力和延性进行了分析;研究了轴压比、钢板箍对装配式连接柱抗震性能的影响.试验表明装配式连接柱的破坏机理与形态和现浇柱有较大的区别,塑性铰区的发展方向完全相反;轴压比是装配式连接柱的延性系数主要影响因素之一,轴压比越小延性系数越大,反之亦然;钢板箍在高轴压比的情况下,更能提高柱子的抗震效果.
In order to study the seismic behavior of the assembled integral type slurry anchor inserted steel reinforcement and steel plate hoop connecting column,2 assembled connecting columns and 2 cast-in-place column models and the low cyclic loading are designed and tested.The assembly connecting the column and a cast-in-place column failure mechanism,failure pattern,hysteresis curves,skeleton curves,deformation,energy dissipation capacity and ductility are also analyzed together with the study of axial compression ratio,steel plate hoop for assembling connecting column seismic performance.Experiments show that the assembly type connecting column failure mechanism and morphology and cast-in-situ concrete column have a big difference,and the plastic hinge zone develops in different directions.Axial compression ratio is assembled connecting column ductility coefficient as one of main influencing factors.The axial compression ratio is small and so is the ductility coefficient.The steel plate hoop in high shaft pressure ratio of the case can also improve the seismic effect.
