PROBLEM TO BE SOLVED: To simplify a measurement system when a damage of a structural material of a beam or the like of a building structure is detected.;SOLUTION: The damage detection system includes: a sensor unit 20 that is installed for each floor slab 10 on each floor of a building structure and measures vertical vibration of each floor slab 10; an eigen frequency calculation unit 106 that converts time history data of a measured value of the vibration measured by the sensor unit 20 into data in a frequency region and calculates the eigen frequency for each floor slab 10; and a damage determination unit 107 that detects variation in the eigen frequency for each floor slab 10 and, on the basis of the detection result, determines whether a damage occurs in a beam around each floor slab 10.;COPYRIGHT: (C)2016,JPO&INPIT
