| Outline of Final Research Achievements |
In this study, we have performed the following studies for the purpose of the advancement of the deterioration diagnosis for the pre-tension PC member that ASR deteriorated. As the first stage, the materials deterioration prediction technique due to ASR deterioration have been examined. In next stage, a bond mode between concrete and PC strand considering ASR expansions has been proposed. At the final stage, we have performed the bending test of the pre-tension PC beam that ASR deteriorated, and a possibility of prediction on the load bearing capacity of it using Non-linear finite element analysis has been shown.
