Computational modelling of failure mechanisms in reinforced concrete structures
A modelling approach for macroscopic reinforced concrete (RC) structures and structural elements under static loading conditions is presented. It uses the embedded modelling technique to separately account for concrete volumes and single longitudinal bars or stirrups. The material equations of the 3D elasto-plastic damage model for concrete are derived assuming isotropic damage, stiffness recovery and loss due to crack closing and reopening and a non-associated flow rule. Suitable material functions and material parameters as well as a regularisation by energy criteria are given. The approach is applied to shear beam tests illustrating numerical results compared to corresponding experimental data.
