| Abstract | ||||
| In this paper, a non-linear finite element analysis is presented to model the behavior of GFRP-reinforced concrete deep beams with and without web reinforcement. The proposed model that integrates the nonlinear material behavior for concrete and FRP is performed by using the software ANSYS 15. The predicted responses are compared in terms of crack pattern and load deflection relation with experimental results. A good agreement is achieved so the proposed approach is considered a tool for simulating GFRP reinforced concrete deep beams. In addition, parametric studies were carried out to investigate the effect of main structural parameters on the behavior of deep beams. It was drawn that; (1) Increasing the concrete strength, or ratio of flexural reinforcement, or horizontal web reinforcement ratio improves the shear strength and the toughness, (2) Vertical shear reinforcement ratio had insignificant effect on shear strength, and (3) increasing shear span-to-depth ratio reduces the shear strength of deep beam. | ||||
