Numerical Simulation of Reinforced Concrete Subjected to Multiaxial Stress Conditions

Reinforced concrete is by far one of the most commonly used construction materials. This composite material demonstrates a highly nonlinear behavior caused by cracking, crushing, aggregate interlock, bond slip, dowel action, shrinkage and creep. Because the reinforced concrete involves so many nonlinear phenomena interacting with one another, the formulation of a "complete" analytical model is very difficult. The focus of this study is cast on: (1) three dimensional nonlinear constitutive relations and failure criterion for concrete subjected to short term monotonic loading; (2) crack modeling in concrete; (3) interface stress and stiffness transfer across the crack; and (4) finite element implementation of the findings into an integrated program. Comparison of numerical results with actual test results are presented to verify this proposed algorithm.
