Abstract
This paper presents an analytical procedure for determining the stress-strain curves of concrete under flexure. The procedure is used to derive the stress-strain curves of confined concrete from tests of thirteen high strength concrete (HSC) columns confined by transverse reinforcement and subjected to different strain gradients. The effects of strain gradient to the stress-strain curves of confined concrete is observed and an analytical model for confined concrete that accounts for this effect is proposed.
