Strong finite element (FE) modeling can capture the nonlinear behavior of RC structures. In this study, Finite Element Analysis (FEA) tool, ABAQUS has been adopted to model the reinforced concrete shear wall with defined boundary conditions. The Concrete Damage Plasticity (CDP) model includes the tension and compression behavior of concrete. The linear behaviour is defined by modulus of elasticity and Poisson’s ratio. The non-linear behaviour in compression and tension is incorporated through the yield stress and crushing strain, yield stress and cracking strain respectively. To incorporate the effect of complex stress state, the ratio of biaxial compressive strength-to-uniaxial compressive strength, the ratio of the second stress invariant on the tensile meridian-to-the compressive meridian, viscosity parameter, eccentricity and dilation angle need to be clearly prescribed. Previous studies show that viscosity µ, dilation angle ψ and eccentricity e are the c important parameters affecting the output to a great extent. As there is a huge disparity in the value of these parameters that need to be incorporated into the model, the present study attempts to demonstrate the influence of viscosity and dilation angle along with eccentricity in capturing the o strength and the failure mechanism of the shear wall. Study shows that a dilation angle of 46 with eccentricity 1.0 could able to capture the diagonal tensile failure of the shear wall considered.
