Abstract
In this work, a consistent formulation for the representation of concrete behavior before and after cracking is implemented into a constitutive model for the analysis of reinforced concrete structures. This formulation, based on non-linear elasticity, is particularly attractive since concrete stiffness matrix is expressed as a function of only two parameters, namely the secant values of elastic modulus and Poisson coefficient, which are properly updated during the analysis. As confirmed by comparisons with experimental data, the followed procedure is able to represent the dilatation and crushing of concrete under compressive loads and, due to its versatile nature, it can be easily extended to fiber reinforced elements.
