| dc.description.abstract | The common type of failure in structural members like beams and corbels is a shear type of failure. Factors like the concrete grade, shear-span–to-depth ratio, percentage of longitudinal and transverse reinforcement makes calculation of shear strength to be complex. Adding fibers increases the complexity of concrete for analysis of shear resistance and formulation of an empirical equation. In this study, shear resistance of chopped glass fiber (30mm) reinforced concrete (GFRC) beams have evaluated experimentally. The loading case was four-point-shear testing which is so called in-plane shear (Mode II) testing. Twenty-four double-edge-notched (DEN) beams have considered. Glass fibers of volume ratio with a percentage of 0.5%, 1%, and 1.5 % with C-20/25 and C-40/50 grades of concrete have studied. The effectiveness of chopped glass fiber for resistance of shear (Mode II) fracture has observed in third (micro-crack localization) fracture stage. Shear resistance at ultimate load have also increased by 9.61%, 18.9%, 27.84% for C-20/25 grade concrete beams and increased by 9.39%, 24.19%, 21.56% for C-40/50 grade concrete beams at level of 0.5%, 1%, 1.5% glass fiber respectively. | en_US |
