Description:
This paper presents the experimental justification of two previously published formulas, Eqs. 2) and 6), for the estimation of the complete stress-strain diagram of concrete. Eq. 2) combined with Eq. 3) differs from the other formulas offered in the literature for similar purpose in that provides more relative curvature in the diagram for concretes of lower strengths. Also, with Eq. 6), it can take the fact into consideration that the value of Σ0 increases with increasing concrete strength. The result of these refinements is that the stress-strain diagrams calculated by these formulas fit better the experimentally obtained diagrams and within wider limits than the similar formulas available in the literature.
