Numerical modelling and analysis of reinforced concrete slab with subsoil

Popis výsledku v původním jazyce

The paper deals with the interaction of reinforced concrete slab with subsoil. The subject of the paper was the processing of nonlinear analysis of the performed experiment. The specifics of the solved task include that it connects the design of concrete structures and geotechnical tasks. It was necessary to take into account the actual behavior of the concrete structure and subsoil. The experiment includes a reinforced concrete slab by dimensions 2000 x 2000 mm, 150 mm thickness. Reinforcement was used netting steel bar 0 8 / 100 mm. For the research task is important, that due to cracking in the reinforced concrete slab, its stiffness bending changes. This change affects the life of the structure due to its degradation. The paper focuses on the comparison of the experiment with the numerical model in two selected load cases. For numerical modeling was used the deformation variant of the finite element method and the 3D computational model. In the computational model, the fracture-plastic material model was chosen for concrete. The Newton-Rapson method was chosen for nonlinear calculation. (C) 2020 American Institute of Physics Inc..
