Chapter 4 - EXPERIMENTAL RESULTS
approximately around 20 đ?‘˜đ?‘ that proves the opening of the main crack in the column inner core. A comparison between the two strengthened samples has been carried out lately and the results are reported in the next table. It shows that, the behavior of the two samples is very similar, considering that the displacement variations for the different đ??żđ?‘‰đ??ˇđ?‘‡đ?‘ are all smaller than 10% except for the đ??żđ?‘‰đ??ˇđ?‘‡đ?‘ 2 and đ??żđ?‘‰đ??ˇđ?‘‡đ?‘ 5 that had recorded higher percentage. 1FRM_SC vs 2FRM_SC [%] 4.6 Lvdt 1 22.0 Lvdt 2 2.2 Lvdt 3 -8.5 Lvdt 4 -45.9 Lvdt 5 0.4 Lvdt 6 5.4 Lvdt 7 -5.3 Lvdt 8 \ Lvdt Top \ Lvdt Bottom Table 4.3.4 - Displacements variation in the strengthened samples.
