METHOD OF MEASURING INTERNAL STRAIN OF CONCRETE STRUCTURE, AND THE CONCRETE STRUCTURE

摘要

PPROBLEM TO BE SOLVED: To provide a method of measuring an internal strain of a concrete structure, capable of measuring the internal biaxial field strain of the concrete structure and capable of surely evaluating the safety of the concrete structure, and to provide the concrete structure. PSOLUTION: In this method of measuring the internal strain of the concrete structure and the concrete structure, a triaxial gage 2 is bonded onto the central part of a cross-shaped part 1, in an acrylic plate 1 provided adjacently with the cross-shaped part, the acrylic plate 1 is embedded into the concrete structure 11, the triaxial gage 2 is made to correspond to the biaxial field strain, and an internal strain state of the concrete structure 11, and the safety against destruction are evaluated even in a complicated stress portion with an unclear main strain direction.
