通过对2根足尺高强连续螺旋箍筋的装配整体式和高强连续螺旋箍筋的现浇柱试件进行水平低周反复加载试验，研究了局部外包钢管栓杆式连接柱的力学特性和破坏模式，对比分析装配整体柱与现浇柱的延性和耗能能力，验证此种连接的装配柱和现浇柱具有同样的抗震性能。对新型连接装配整体柱进行有限元分析，研究外包钢管壁的厚度，长度以及柱的轴压比对装配整体柱的承载能力的影响。

Two specimens of the high-strength continuous spiral stirrups assembled monolithic and the monotonic were tested under low-frequency cyclic lateral loading.The mechanical properties and failure modes of the assembled monolithic specimens were analyzed based on the experimental study.Through comparison of the overall ductility and energy dissipation capacity between the assembly cast columns and assembled monolithic columns,the results indicate that the anti-seismic property of the assembly cast column is not worse than the monotonic specimen.The finite element analyses of the new connections were also performed.The carrying capacity of the column were investigated for different outsourcing steel thickness,lengths and axial compression ratios.
