Modeling of nonlinear behavior and failure of concrete is a crucial aspect for reliable simulation of reinforced concrete structures. A new microplane formulation provide a way to model the behavior of concrete by defining constitutive model between stress and strain vectors on arbitrary oriented planes. A gradient enhanced element with coupled damage-plasticity microplane material is used to model the concrete behavior. The steel reinforcement will be simulated using one dimensional elements and a plastic material model. The incorporation of nonlinearities both in the concrete and in the steel reinforcement, as well as the use of a nonlocal formulation enable simulation of concrete under a wide range of loading situations as cyclic loading. Studies on model parameters and their identification will be performed to have an initial prediction about the effect of changing model parameters. A parametric study of a reinforced concrete column subjected to axial and cyclic shear loads is performed. The proposed microplane model shows a great capability of modeling cyclic loading. The damage split formulation can retrive the lost stiffness when changing from tension to compression stresses.
