摘 要:研究了GFRP纵筋与GFRP箍筋共同作用、GFRP管与GFRP筋共同作用对海水海砂混凝土(SSC)柱轴压性能的影响。结果表明:随着GFRP纵筋配筋率的增加,SSC柱的极限承载力相比对照组提高了4.3%~49.8%;采用GFRP管与GFRP筋共同增强后,SSC柱的承载力和延性进一步提高,试件破坏后整体形状完整,破坏形式得到了改善。
Abstract: The effects of the interaction of GFRP longitudinal bar and GFRP stirrup and the interaction of GFRP pipe and GFRP bar on the axial compressive behavior of seawater sea sand concrete(SSC) columns were studied. The results show that with the increase of GFRP longitudinal bar ratio, the ultimate bearing capacity of SSC column increases by 4.3%~49.8% compared with the control group. The bearing capacity and ductility of SSC column are further improved after GFRP pipe and GFRP bar are used, and the overall shape of the specimen after failure is complete and the failure form is improved.
