摘要
通过低周反复拟静力试验方法,研究钢板箍螺栓连接装配整体式柱的抗震性能。试验共设计4根长柱试件,观察各试件开裂、屈服、破坏全过程和破坏状态,得出各试件荷载-位移滞回曲线和骨架线,对比研究各试件承载力、延性和耗能能力,研究钢板箍螺栓连接方式的可行性。试验证明:钢板箍螺栓连接高强复合螺旋箍筋装配整体式柱和现浇整体柱具有相当的承载力和抗震能力,在连接可靠的情况下可以在工程中代替现浇柱。
In order to study the seismic behavior of steel plate hoop-bolt prefabricated column by high-strength composite spiral stirrups , the low cyclic loading tests were carried out .Four long column specimens were designed . Cracking, yield, destroyed process and destroyed state of specimens were observed in the tests , and the load-displacement hysteretic curves and skeleton curves of each specimen were also obtained .Comparative study on carrying capacity , ductility and energy dissipation capacity of each specimen was conducted , and analysis of the reliability of steel plate hoop-bolt connection was done .The test proves that steel plate hoop-bolt prefabricated column confined by high-strength composite spiral stirrups has about the same bearing capacity and seismic capacity as compared with cast-in-place column, and the prefabricated column can be used to replace the cast-in-place column in project in case of secure connections .
