Fig. 4. Measured and calculated Fig. 5. Poly linear softening curves load-displacement curves of typical concrete specimens
The poly linear softening curves of the BA, Sil%, SI2%, SI3%, ST0.5% and STl % concrete specimens are plotted in Fig. 6. The tensile strength values of the basic (BA) and fiber reinforced concretes, as calculated by best fit, are slightly higher than those determined using cylindrical specimens. The tension softening curves in Fig. 6 clearly show that the
