This paper presents an experimental and theoretical analysis of three dimensional (3D) finite element (FE) model to predict the shear strength, load-deflection, and crack pattern of fourteen Hybrid Glass Fiber Reinforced Polymers (GFRP)/Steel Bars in Reinforced Concrete Beams without stirrups by ANSYS. The reinforced concrete beams are simply supported, All beams cross-sections were of 120 mm breadth and variable depth, the overall length was 2300 mm with a clear span of 2000 mm without stirrups The main variables considered were; the reinforcement ratio (ρ), shear span to depth ratio (a/d), depth of beam (d) and concrete compressive strength (f_c').In hybrid GFRP/steel reinforced concrete beams, a significant improvement in ductility and a noticeable decrease in the beams’ deflection and deformation. On the other hand, hybrid GFRP/steel reinforced concrete beams showed better performance during cracking initiation and propagation. The ANSYS results were compared to the experimental results conducted by the authors to ensure that the finite element model was accurate. The FE models' theoretical conclusions are in good agreement with the experimental results. Each parameter's effect was described and compared to experimental results.
