Abstract | This study investigated the behavior of hollow concrete columns (HCCs) reinforced with glass fiber-reinforced polymer (GFRP) bars and spirals under axial loading. Nine columns were constructed with a hollow circular cross section having 305/113 mm outer/inner diameter and 1500 mm height, while five solid columns were fabricated as references. Test parameters included the influence of the longitudinal reinforcement ratio (1.89, 2.53, and 3.79%), type (GFRP and steel), and cross-section configuration (hollow and solid) on the behavior of HCCs. The test results show that increasing the reinforcement ratio had no significant effect on the peak load but significantly enhanced the confinement efficiency and ductility of the HCCs reinforced with GFRP bars and spirals. The GFRP longitudinal reinforcement contributed to resisting the peak loads by an average of 11% of the ultimate capacity. Thus, considering the contribution of GFRP bars in the recent design guidelines can safely estimate the ultimate capacity of the HCCs. |
