FRACTURE ENERGY OF CONCRETE
Thus the value Gft, = G,o[1 + \)1(00)] is an ef fective fracture energy representing the crack growth resis tance for a very large structure. By perturbation theory, Planas et al. (1992) estimated for a certain concrete that \)1(00) = 0.0445, which is a rather small correction.
