AbstractIn this paper, a novel constitutive model of concrete has been proposed by introducing a new parameter, namely, cracking Poisson's ratio (νcr), to account for the effect of localization due to cracking. By fitting the curve between the dimensionless strain (ε/εpr) and cracking Poisson's ratio (νcr), νcr can be expressed as an 3rd order polynomial function of dimensionless longitudinal strain (ε/εpr). The constitutive model for the softening regime can then be proposed with the parameters of dimensionless strain and cracking Poisson's ratio. Finally, Validity of the proposed model is verified by the test results of cylinder specimens of C30. © (2010) Trans Tech Publications.
