| Outline of Final Research Achievements |
This study dealt with repair and strengthening methods in order to conserve historical structures: concrete revetment, industrial facilities and RC buildings in Gunkanjima island. Estimation of material and structural soundness, performance evaluation of repair and strengthening materials, and development of new repair and strengthening methods carried out. As a result, it was found that shore concrete has enough material soundness though some cracks in revetment and gaps between strengthening concrete and masonry have progressed. Moreover, it was clarified effectiveness of surface impregnation materials. CFRP anchor-truss structure and high-performance concrete box press joint structure are proposed.
