I need to know what is the suitable constitutive model for reinforced concrete in shear walls with openings in the FEM Program ABAQUS.
The shear walls are with different openings configuration and subjected to axial and lateral forces.
I need to implement vertical and horizontal (confinement) steel reinforcement.
Dear Hossam
You can use bothe models and they can give your desired result. However, in my experience I prefer to use CDP.

The smeared crack model is usually used to model the cracked zone, while the plasticity model is used to control and check the stress status at any point, whether it is under uniaxial, biaxial or triaxial state of stress. This check is to be done at every integration point, while the cracked model is used in the tension zone.
Concrete damaged plasticity model was developed to provide a general capability for the analysis of concrete structures under cyclic and/or dynamic loading. While the concrete smeared cracking model is mainly applicable to static monotonic loading.
