| dc.description.abstract | In reinforced concrete members, reinforcement must be bonded or anchored to the concrete. Reinforcement development length is provided in the regions of maximum stress to zero stress. However, at the support of simply supported beam, the bending stress is zero, the researchers recommend that the longitudinal reinforcement should develop farther from the support to resist pullout of bars. The research focuses on the investigation of the effect of longitudinal reinforcement end anchorage angle and development length from the support on simply supported beam capacity. The investigation was conducted on three shear critical and three flexure critical beams using experiment and finite element analysis software. The experimental and the finite element analysis result gives comparable result for each beam. The result shows that the development of a longitudinal reinforcement bar farther from the center of support and use of 135 o end anchorage angle has no significant effect on flexure critical beams capacity and crack pattern formation. But, use of development length and different end anchorage angles on longitudinal reinforcement bars have a significant effect on the ultimate load capacity and crack pattern formation on the shear critical beams. The ultimate capacities of beams having longitudinal reinforcement 135 o or 90 end anchorage and beams without development length from the support reduced by 11.75% and 29.05% from the ultimate capacities of beams having 90 o end anchorage respectively. Also, shear critical beams give different crack pattern formation due to the variation of reinforcement bar end anchorage angle and development length. | en_US |
