3D Numerical Modeling of RC Deep Beam Behavior by Nonlinear Finite Element Analysis

Abstract

In order to investigate behavior of reinforced concrete deep beams under static and dynamic loads, conducting a finite element analysis in comparison with an experimental study is very preferable and reliable technique from the viewpoint of difficulty, time saving, human force and budget. The main motivation of the study is to propose a numerical finite element model, including a reliable finite element modeling technique and constitutive material models, to simulate nonlinear behavior of reinforced concrete deep beams. For this purpose in the study, a nonlinear finite element analysis is performed to represent behavior of reinforced concrete deep beams. An existing experimental study is selected from literature and one of the tested specimen of it is verified numerically. Numerical results are compared with experimental ones in terms of load-displacement and damage distribution behaviors. Analysis are performed by using a commercial FE program named ABAQUS. The analysis results are demonstrated that finite element analysis is a highly effective and reliable tool to simulate nonlinear behavior of reinforced concrete deep beams.
