Abstract:

When strengthening the negative moment area of a reinforced concrete (RC) beam, the presented anchorage would be insufficient because the carbon fiber reinforced polymer (CFRP) strips will be cut-off at the place of column. For this reason, strengthening effectiveness of several bonding methods is discussed in this paper based on tests. The supports of continuous beam of the vertical axis from different parts of the carbon fiber strain changes has been studied. By inspection of wing plates in different parts of the CFRP structural capacity increase of the contribution of difference, useful conclusions are obtained.

Key words: carbon fiber reinforced polymer (CFRP); reinforced concrete (RC) continuous beams; strengthening; negative moment area
