Seismic Performance of Precast Segmental Bridge Columns Reinforced with Both Stainless-Steel Bars and GFRP Bars

An innovative precast segmental bridge column (PSBC) was proposed to achieve a better durability performance in an aggressive coastal environment, which was reinforced with both longitudinal stainless steel (SS) bars and glass fiber reinforced polymer (GFRP) bars. Four 3/20-scale PSBCs with various ratios of GFRP to SS bars were tested quasi-statically. Test results showed that compared to SS-reinforced PSBCs (SR-PSBCs), the SS-GFRP-reinforced...
