Numerical study on the shear strength of reinforced concrete beams using ABAQUS

In the field of structural engineering, numerical techniques are widely employed to provide approximate solutions to complicated issues. The finite element approach is the name given to this methodology. It generally breaks down structural members into exceedingly small elements. Nonlinear finite element analys is often yields appropriate estimates of structural output findings and can correctly account for the basics of structural analys is and design theory. In recent years, finite element analysis has become increasingly popular, especially as computer technology advances. The construction of 3D nonlinear finite element models of reinforced concrete beams subjected to shear behavior is discussed in this article. These finite element models were created and analyzed using the ABAQUS software version 2019. When compared to experimental data in the mechanism of failure, load capacity, and load-deformation, the Finite Element Analysis results demonstrated satisfactory agreement in general behavior. The experimental ultimate load capacity was 1.9 % lower than that predicted by the ABAQUS computer program, on average. While the difference in deflection at ultimate loads between the experimental test and numerical outcomes was 2.3%, on average. The failure mechanism, load capacity, and load-deformation of the beams all show that FE analysis may be a good estimation with a powerful ability to mimic cracking and damaging processes that are similar to experimental investigations.
