A reinforced concrete material model that includes frictional bond-slip behavior and shear friction behavior is proposed for use in a 2D total-strain based finite element analysis. The motivation for this model is to improve both tension stiffening behavior and shear strength and stiffness of total-strain based models. The proposed bond/slip membrane model is based on a simplified mechanistic concept and is capable of modeling bond/slip behavior under cyclic loading in a smeared manner. This dissertation presents a FEA implementation of the proposed bond/slip based material model in the OpenSees framework. The model is validated with shear wall test results available in the literature. Another motivation for this model is to understand the significance of crack strains so that the model can be extended to include shear friction behavior for cracked concrete. A shear friction model is developed and implemented for 1-directional cracking. Based on the results of the bond/slip model, the shear friction model is implemented as a total strain based model rather than as a crack strain based model. This greatly simplifies the implementation. This is the first FEA material model that is able to capture fundamental shear/friction behavior by enforcing a relationship between crack slip and separation.
