Table 9: The effects of the CFRP layers on the restraint of static and dynamic hoop strains. seconds of the excitation in the 530 mm filling height specimens. However, sloshing occurred more strongly in the 265 mm filling height specimens because the maximum excitations were higher in these cases. Figures 15 and 16 show the dynamic hoop strains in the vertical direction for all the specimens that were filled to 530 mm and 265 mm heights, respectively. Figures 17-22 show the dynamic hoop strains in the horizontal direction for these specimens. The maximum values of the dynamic hoop strains in the horizontal direction were almost in the excitation direction. A small difference occurred for DUT0-530 and DBT0/90-530, where the maximum values of the dynamic hoop strains were on the right side of the excitation direction position (see Figures 18 and 19). The difference was caused by the geometrical imperfections when installing the specimens and were confirmed by the values of the static strains (Figure 12) since the static strain values on the right side of the excitation direction position were also higher compared to the excitation direction position. However, these differences were very small and the maximum dynamic strain values could also be considered to be located in the excitation direction position for the DUT0-530 and DBT0/90-530 specimens. While the same experimental conditions were applied for the DNS-530, DUT0-530, and DBT0/90-530 specimens, the difference did not occur for DNS-530 specimens because the strain values were much higher in the DNS-530 specimen compared to the DUT0-530 and DBT0/90-530 specimens. Therefore, the maximum dynamic strain values could be seen in the excitation direction position for the DNS-530 specimen. The maximum values of the dynamic hoop strains in the horizontal direction were in the excitation direction for all 265 mm filling height specimens because the specimens were highly impacted by stronger sloshing.

The effects of the CFRP layers on the restraint of the dynamic hoop strain values for all specimens are also shown in Table 9. The dynamic strain values are the average values of the three tests.
