The deformation-based damage limits and plastic rotation properties of reinforced concrete square column models according to ASCE/SEI 41-17 and nonlinear displacement capacities according to displacement-based seismic performance evaluation procedures were analytically investigated.Reinforced concrete square column models were designed to analytically investigate the effects of various design parameters such as concrete grade, transverse reinforcement ratio and axial load levels on the nonlinear displacement and deformation damage limits.According to the results obtained from the nonlinear behaviour relations, the deformation damage limits and plastic rotation properties for the IO, LS and CP performance levels and the force-deformation relations of the designed column models according to different parameters according to ASCE/SEI 41-17 were obtained and compared.The results obtained from the analysis for each section of the whole study were interpreted by comparing them.In the performance evaluation of reinforced concrete structures, the deformation demands, that are taken into consideration as a basis are very important in order to determine the damages of the carrier elements.It has been concluded that the transverse reinforcement ratio and axial load levels have significant effects on the nonlinear behaviour of the reinforced concrete column models, section damage limits and plastic hinge properties, displacement capacities and force-strain relationships.
