Abstract:
A reinforced concrete (RC) material model that includes frictional bond-slip behavior is proposed for use in a two-dimensional (2D) total strain-based finite element analysis (FEA). The initial motivation for this model is to improve tension stiffening behavior in total strain-based models. The proposed material model is based on a simplified mechanistic concept and is capable of modeling these mechanistic behaviors under cyclic loading in a smeared (average) manner. It is validated with shear wall test results available herein. Another motivation for this model is to understand the significance of crack strains so that the model can be extended in the future to include shear friction behavior for cracked concrete. This paper presents an FEA implementation of the proposed RC material model in the OpenSees framework.
