Abstract
Structural engineers frequently employ numerical techniques to provide approximate solutions to complex problems. This methodology is known as the finite element approach. It often collapses structural components into very small parts. Fundamental concepts of structural analysis and design theory are successfully included in nonlinear finite element analysis, which frequently yields accurate predictions of structural behavior. Recent advances in computer technology have contributed to the rise in popularity of finite element analysis. This article discusses the creation of the 3D model of nonlinear finite element for RC beams with shear behaviour. We generated and evaluated the finite element models using the ABAQUS program, specifically version 2019. The findings of the Finite Element Analysis for the strain distribution, load deflection relationship, modes of failure, and load capacity were mostly consistent with the experimental data. The experiment's actual maximum load capacity was, on average, 2.75%, lower than the figure that the ABAQUS computer algorithm projected. The practical trial and computational results showed a mean deflection difference of 7.54% at ultimate loads. Finite element (FE) analysis might be a good way to make estimates based on the beams' cracking behaviour, load-bearing capacity, and deformation characteristics. This is due to its ability to properly simulate crack propagation and structural damage, resembling the outcomes of actual investigations.
