To provide a concrete structure examining and diagnosing method of a simple constitution capable of highly accurately examining and diagnosing concrete structures and being applied to even large-scale concrete structures.
On the basis of a frequency-strength distribution measured by a vibration sensor 2 attached to a concrete structure 1 to be inspected, the geometric features and properties of the concrete structure 1 are examined and diagnosed. In addition, by comparing the frequency-strength distribution measured on the concrete structure 1 with a frequency-strength distribution measured on a concrete structure of which the geometric features and properties are known, the geometric features and properties of the concrete structure 1 are examined and diagnosed. Furthermore, by attaching the vibration sensor 2 to different sections of the concrete structure 1, measuring a frequency-strength distribution at each section, and comparing the frequency-strength distributions with one another, the geometric features and properties of the concrete structure 1 are examined and diagnosed.
