Abstract: Analytical models for the stress-strain relationship of confined and unconfined concrete in compression are required for modeling the structural behavior of the reinforced concrete structural elements. The presented paper reviews the widely used models by Attard & Setunge (1996) and Binici (2005) and compares them with test results on uniaxial and triaxial tests with different specimen heights and widths and concrete strength. The variation of peak stress and corresponding strain, as well as the residual stress level, under confinement are compared with experimental results and discussed. A new analytical model is introduced which tries to address the limitations in previous models. The proposed model is capable of predicting the behavior of normal strength as well as high strength concretes.
