Abstract

Reinforced concrete demonstrates a highly nonlinear behavior caused by cracking, aggregate interlock, bond slip, dowel action, shrinkage, creep, etc. Today with the help of computer, the finite element method offers a powerful tool for studying reinforced concrete structures. However, the success of such analyses depends on thorough understanding and modelling of the composite material behavior. In this study, an elastic strain hardening plastic model is derived for concrete. The stress-strain behavior for reinforcement is modeled as an idealized bilinear curve. For cracked reinforced concrete, the smeared crack system is adopted. Two types of crack models, fixed crack model and rotating crack model, are formulated and tension stiffening, stress degrading effect parallel to crack direction and shear retention have all been included. Through a layering approach these material models are further extended to model the flexural behavior of reinforced concrete structures. These reinforced concrete material models have been tested against the experimental results and it is demonstrated that they are suitable to model the behavior of reinforced concrete structures.
