Three classical concrete stress-strain curves were evaluated against the experimental results. Some ABAQUS inputting parameters of concrete materials were investigated. Some valuable advices were promoted for choosing concrete stress-strain curves and inputting parameters.Keywords: concrete; stress-strain curves; cyclic loads; ABAQUS; damaged plasticity; numerical analysis
