| Summary: | This paper presents the experimental results of shear behaviour on concrete beams
longitudinally reinforced with glass fiber-reinforced polymer (GFRP) reinforcement bars. Totally
sixteen concrete beams were tested under static load. Half of the tested beams were longitudinally
reinforced with GFRP reinforcement bars, while, the other half were reinforced with conventional
steel reinforcement bars. The beams were prepared with varying test variables, such as shear spanto-
effective depth ratios (a/d), amount and types of longitudinal reinforcement bars and stirrup
spacing. The experimental results show that the ratios of a/d and stirrup spacing significantly
influence the ultimate capacities of the beams. Moreover, more closely spaced diagonal shear
cracks were resulted in GFRP reinforced concrete (RC) beams compared to steel RC beams. |
