PROBLEM TO BE SOLVED: To measure a large distortion and a greatly deformed area generated in a structural member by an earthquake disaster, and to quickly, objectively and precisely determine a degree of damage in the structural member and the possibility of continual use after an earthquake. SOLUTION: Sensor members 2 such as optical fibers and conductive members having different breaking characteristics are laid in the structural member 1, the number of broken sensor members is acquired as a data after the earthquake, and the degree of damage in the structural member is determined based on the data.
