The problems taken into account are: a choice of proper material model for concrete, establishing of compressive and tensile behavior of concrete and establishing the values of dilation angle, fracture energy and relaxation time for concrete. Proper values of material constants are fix ed in simple compression and tension tests. The effectiveness and correctness of applied model is checked on the example of reinforced concrete frame corners under opening bending moment. Calculations are performed in Abaqus software using Concrete Damaged Plasticity model of concrete.}, abstract={}, type={Artykuły / Articles}, title={Wybrane aspekty komputerowego modelowania konstrukcji żelbetowych}, title={Selected aspects of computer modeling of reinforced concrete structures}, URL={http://www.czasopisma.pan.pl/Content/84071/mainfile.pdf}, keywords={model plastyczny z kontynualnym uszkodzeniem, ABAQUS, naroża ram, moment otwierający, kąt dylatancji, czas relaksacji, concrete damaged plasticity, Abaqus, frame corners, opening bending moment, dilation angle, relaxation time}, }
