Comparative study of finite element methods of calculation of ribbed reinforced concrete floors

The paper presents the results of a comparative study several finite element models ribbed reinforced concrete solid floors. Using example slab with infrequent ribs arranged along grid columns, three frequently used in computational practice are analyzed. Those include both rods and thin-walled elements. In first model, plate its considered separately, within framework decomposition scheme structure. second model contains elements rod connected to each other. third consists entirely that floor ribs. is also formulation problem theory elasticity. represented form rigidly bodies plates. Reinforcement inside massive included as separate bodies. This serves benchmark for assessing accuracy obtained results. Its calculation performed FEM application Ansys. compares calculations using various models. A conclusion made about significant difference between proposed work similar studies devoted selection best design schemes consideration influence reinforcement on behavior
