摘要
To reduce a calculation load when fatigue damage evaluation of a device used for a structure is performed.SOLUTION: A system includes a measuring device 11 for measuring an earthquake response of a reactor building or the like in the event of an earthquake, a cumulative maximum amplitude equivalent number calculating part 21 for determining a cumulative maximum amplitude equivalent number, which is an accumulated maximum amplitude equivalent to a maximum amplitude equivalent number as a maximum value of a target frequency range of the equipment used for the building or the like based on the measured value measured by a measuring device 11, and a cumulative fatigue damage degree calculating part 22 for determining the cumulative fatigue damage degree of the device by the first comparing part 212, when the cumulative maximum amplitude equivalent number is equal to or larger than a threshold value on the device 212, by using a cumulative maximum amplitude equivalent number and the like, which are an accumulated maximum amplitude equivalent number and a cumulative maximum amplitude equivalent number of times as a maximum amplitude equivalent to the target frequency range of the equipment used in the building or the like, based on measured values measured by the measuring device 11.SELECTED DRAWING: Figure 14
