Claim 4:
5. A structure deterioration detection method comprising:
a step of continuously monitoring a structure to detect any vibration along a longitudinal direction of the structure by a sensor unit placed along the longitudinal direction of the structure, the vibration being generated when at least one moving body is moving along the structure;
a step of measuring a strength of the detected vibration by a measurement unit;
a step of integrating a measured vibration strength for a specified period of time by an integration unit;
a step of storing an integrated vibration strength by a storage unit;
a step of measuring the number of moving bodies by a count unit; and
a step of making a determination about whether deterioration of the structure has occurred by a variation of values obtained by standardizing integrated vibration strengths by the number of moving bodies at different times by a determination unit.
