Abstract :
This paper presents a numerical investigation of Hybrid FRP-reinforced concrete beams. A nonlinear finite element (FE) model is developed using the commercial software package ABAQUS to simulate the ductility and flexural behavior of steel, GFRP and Hybrid-reinforced beams subjected to 3 point bending. The present FE results including the flexural capacity, failure mode and load deflection curves are verified and compared with previously published experiments. The main purpose of the present FE model is to extend the numerical analysis and conduct a parametric study in the future. The present numerical analysis consisted of ten concrete beams of 4 meter length subjected to 3 point bending until failure. The effects of the adding steel reinforcement to FRP reinforced beams are investigated and compared to a reference GFRP and steel reinforced beams.
