Nonlinear Analysis of Reinforced Concrete Structural Elements

Nonlinear analysis of reinforced concrete elements is the focus of the present study. A concrete damage plasticity model available in Abaqus commercial software has been modified using user defined modules to include the concrete stiffness degradation and growth in the Poisson’s ratio in plain concrete with increase in compressive strain. In reinforced concrete the degradation of cracked concrete in compression, tension stiffening effects and bond slip have been considered to enhance the prediction of responses observed in reinforced concrete elements under various loadings. The model predicts the salient features of multiaxial response observed in experiments on plain and reinforced concrete elements subjected to various loads.
