Abstract | Limited experimental studies have been implemented to examine the performance of hollow concrete columns (HCCs) reinforced with glass fiber-reinforced polymers (GFRP) reinforcements. This study investigated the performance of four large-scale HCCs that were tested under concentric load. These columns were reinforced in the longitudinal direction with eight GFRP bars No.5 and with different transverse reinforcement ratios (nil, 0.75, 1.10, and 2.20%), which were achieved by changing the spiral’s pitch (no transverse reinforcement, 120, 80, and 40 mm). The 305/113 mm outer/inner diameter columns were designed according to Canadian design code requirements. The objective of the study was to investigate the effect of the transverse reinforcement ratio (in terms of the spiral’s spacing). The test results indicated that the GFRP-RC hollow columns exhibited a compression failure in terms of concrete cover spalling, and the GFRP reinforcement remained undamaged up to the failure. The GFRP longitudinal reinforcement significantly contributed to resisting the peak loads in all tested columns, on average 11% of the ultimate carrying load. It also was found that increasing the transverse reinforcement ratio from 0.75 to 2.20% increases 8–14% in the peak and 1.60–1.90 in the confinement efficiency. |
