With the invention of sophisticated numerical tools for analysis like the finite element method (FEM), it has become possible to model the complex behavior of reinforced concrete members using Finite Element modeling.

Abstract. This article presents a finite element analysis of reinforced concrete deep beams using nonlinear fracture mechanics. The article describes the development of a numerical model that includes several nonlinear processes such as compres sion and tension softening of concrete, bond slip between concrete and reinforcement, and the yielding of the longitu dinal steel reinforcement.
