摘 要:研究了GFRP縱筋與GFRP箍筋共同作用、GFRP管與GFRP筋共同作用對海水海砂混凝土(SSC)柱軸壓性能的影響。結果表明:隨著GFRP縱筋配筋率的增加,SSC柱的極限承載力相比對照組提高了4.3%~49.8%;采用GFRP管與GFRP筋共同增強后,SSC柱的承載力和延性進一步提高,試件破壞后整體形狀完整,破壞形式得到了改善。
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.
