| Research Abstract |
In Hokuriku region, when doing maintenance management of concrete structure, we should consider the alkali-aggregate reaction. In the diagnosis technology of such a concrete structure, it is necessary that the cost of method is low and that method is suitable against the deterioration states. This study considered the measurement method of the expansive strain using the stress releasing method by core boring. As the results, we confirmed that the released strains of concrete were measured by using buried sensor. Moreover, we confirmed that the strains of steel bars and concrete were estimated by using 3D stress analysis.
