| Outline of Final Research Achievements |
Influence of corroded bond action and cycle loading to flexure behavior of corroded RC beam is investigated. Effect of corrosion crack in compressive area is also investigated.
In the result, it is clarified that loss of rib on re-bar and corrosion crack which does not appear on beam surface give no influence to ultimate deformation in flexure. Wider corrosion crack appearing on beam surface decreases ultimate deformation in the flexure. In FEA, corrosion crack model expressed by initial cracking and interface element does not evaluate failure behavior seen in the experiment because an effective area in compression zone in the analysis is decreased by the corrosion crack model. Therefore, more effective model is required to evaluate the influence of corrosion crack in compression sone to the flexural failure behavior of RC beam.
