Sažetak
The paper shortly presents numerical model developed for simulation of composite structures. The main structure is modeled with two-dimensional plane elements, while the composite surface is modeled with two-dimensional interface elements for continuous connection simulation and modified beam elements for discrete connection simulation. The applied material model was used for the purpose of simulation of reinforcing concrete structures. It includes the most important nonlinear effects of reinforced concrete behavior: yielding in pressure and opening and propagation of cracks in tension with tensile and shear stiffness of cracked concrete, as well as nonlinear behavior of reinforced steel. It also includes nonlinear behavior of composite surface and connection elements (dowels). The model was confirmed on experimental tests of composite concrete (Omnia) slabs, which are common in usage. The obtained test results were compared with the results obtained through the numerical model.
