Contribution to the modeling of the cyclical and monotonic behavior of reinforced concrete structures

Abstract : The present paper deals with the behavior of reinforced concrete beams in presence of plasticity and cyclic loadings. The model takes into account the nonlinear material behaviors of the constituents steel and concrete. A numerical model based on the finite element method is investigated for the study of the reinforced concrete beams under cyclic loads undergoing large deformation in the plastic range. In the study, nonlinear material behavior laws are introduced in presence of plasticity and cyclic behavior in the concrete in compression and in the reinforcement steel bars under tension stresses. The concrete steel interactions as well as the crack damage are also considered in the model. An incremental iterative method in adopted in the solution of the equilibrium equations. The model is validated and compared to some benchmark solutions available in literature. The agreement is good in the case of beams under monotonic loads or cyclic loads with high cycles.
