Abstract
Performance of glass fiber reinforced polymer (GFRP) reinforced high performance concrete compression members under axial loading were studied by conducting detailed experimental investigations. For the present study, twenty-four square columns of size 150 mm and slenderness ratios of 6, 8, 10 and 12 were cast, in which twelve columns reinforced with GFRP and the remaining twelve with conventional steel. For each slenderness ratio, three different percentages of reinforcement was tried with 1.4%, 2% and 3.5% each as longitudinal reinforcement for both GFRP and steel. Performance characteristics such as load carrying capacity, axial deformation, lateral deformation and rebar axial strain were studied in detail. Parametric study was done taking L/D ratio and percentage of reinforcement as parameters. Keywords: Load carrying capacity, axial deformation, lateral deformation, rebar axial strain, L/D ratio, Glass Fiber Reinforced Polymer
