Sažetak
The aim of this paper is to present the application of the FDEM in analysis of 2D and 3D RC structures. In presented numerical model, the reinforcing bar finite elements are implemented within the concrete finite elements and simulate the behavior of the reinforcing bar within the uncracked concrete assuming the linear elastic behavior of the reinforcing bar in the concrete finite element and a perfect bond between the concrete and the reinforcing bar. Fracture and fragmentation as well as material nonlinearity are described with contact elements for concrete and contact element for reinforcing bars which are implemented within the finite element mesh. The model, implicates few numerical algorithms which are based on approximation of the experimental curves for material behavior of the concrete and steel which are important for description of main non-linear effects in reinforced concrete structures. In presented model non-linear material model for steel is based on experimental stress-strain curve, while the cyclic behavior of the steel during the cyclic load is modelled with improved Kato’s model.
