Abstract
This article conducts a theoretical and experimental analysis of three dimensional (3D) finite element (FE) model to anticipate 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. In this paper, the adopted variables are; concrete compressive strength (fc'), shear span to depth ratio (a/d), depth of beam (d), and the reinforcement ratio (ρ). In hybrid GFRP/steel reinforced concrete beams, the experiments demonstrate a significant improvement in ductility and an apparent decrease in deflection and deformation of the beams. In contrast, during cracking initiation and propagation, better performance is found in hybrid GFRP/steel reinforced concrete beams. A comparison is conducted between the results of the ANSYS and the experiment to ensure that the finite element model is accurate. Additionally, each parameter's effect was described and compared to experimental results. The FE models’ theoretical conclusions are in acceptable agreement with the experimental outcomes.
