Test Results And Discussion

After test, all specimens revealed the complete detachment of the reinforcement from the support. The failure involved the brick surface (Fig. 4), where curved cracks and ripping of clay pieces were observed.

The failure loads, Pu, are given Tables 3-4 and plotted in Figure 5. It is possible to note as specimens strengthened with CFRP showed better performances than GFRP one. The mean failure load in the first case was around 35% higher than the latter.
