A nonlinear material model for cracked reinforced concrete subjected to inplane shear and normal stresses has been developed. As a result, a set of constitutive equations suitable for incremental finite element analysis is derived. Features of the present model include the smeared crack representation, rotating crack approach, tension stiffening, stress degrading effect for concrete parallel to the crack direction, and shear retention of concrete on the crack surface. This material model has been tested against the experimental data of Vecchio and Collins and it has been demonstrated that this material model is adequate in describing the post-cracking behavior of reinforced concrete.
