A Review of mathematical models for prediction of Stress-strain and moment –curvature behaviour in concrete

In this paper, a mathematical model for predicting the stress –strain and moment curvature relations in concrete is developed. A good number of empirical equations were proposed to represent stress-strain behaviour of conventional concrete. Most of the equations can be used for the ascending portion...
