Abstract

It was achieved to formulate numerically the stress-strain relationship of concrete, which is a fundamemtal factor for the Elasto-Plastic analysis of concrete structures, for normal concrete by using random statistics. As a result of experiment, in the shape of stress-strain curves of normal concrete it has approach linear from first loading to peak point, and after that point deformation increased radically and specimens were brokendown abruptly. From the multiple linear regression, and obtained the exponential equaion for stress-strain relationship of concrete as follows: $\sigma$/$\sigma$max=e(1-$\varepsilon$/$\varepsilon$max)$\varepsilon$/$\varepsilon$max
