Abstract: In this study, stress-strain relationships for confined reinforced concrete columns were investigated according to TBEC 2018 and Mander models. Confined concrete compressive strength and stress-strain relationships have been investigated for concrete columns according to the proposed confined concrete models. In order to better understand the behavior of the confined concrete, stress-strain relations and information about the confined concrete models are given. To investigate the behavior of confined concrete, square cross-section reinforced concrete column models with different transverse reinforcement diameters and spacing have been designed. The effect of the diameter and spacing of the transverse reinforcement on the confined concrete compressive strength was investigated. Stress-strain relations of square cross-section columns were investigated by considering the different confined concrete models. The stress-strain curves were obtained by calculating the confined concrete compressive strengths and strain at maximum concrete stress in the square cross-section column models designed. The results obtained from the analysis results were compared and interpreted according to different parameters. Results obtained with TBEC 2018 and Mander model were compared and interpreted. It has been concluded that the use of transverse reinforcement with different diameters and spacing in the models affects the lateral confining stress on core concrete from transverse reinforcement and compressive strength of confined concrete in column sections designed with different parameters. © 2021, TUBITAK.
