摘要
对新型连接装配柱和现浇柱进行拟静力试验,验证此种连接的装配柱和现浇柱具有同样的抗震性能。采用ANSYS有限元软件对局部外包钢板箍高强箍筋约束混凝土栓筋式柱与柱连接进行滞回数值分析,并与低周反复加载试验的滞回试验结果进行比较,研究新型柱柱连接节点的受力特点,进而在大量数值模拟的基础上,归纳总结出相关参数对整体装配柱抗震性能的影响程度,对在实际工程中的应用提出相关建议。
Experiments of two assembled connecting columns and two cast-in-place column models under low cyclic loading and different axial compressive forces are carried out .The result testified that the anti-seismic property of this measure is not worse than the monotonic specimens and can substitute for the monotonic columns in practice .The finite element software ANSYS is used to verify the experimental result of the specimens .By the research on the mechanical characteristics of new connecting columns , the effects of related parameters on the seismic performance of the assembly column are summarized on the basis of numerical simulations .The proposals were put forward on practical engineering applications .
