DAMAGE DEGREE DETERMINATION DEVICE AND DAMAGE DEGREE DETERMINATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To determine damage degree of an industrialized structure rapidly and easily.;SOLUTION: The damage degree determination device has: a natural frequency calculation unit for calculating, for an industrialized structure that can be designed by setting a part of design elements, a first natural frequency in a first predetermined period and calculating a second natural frequency in a second predetermined period after the first predetermined period; a change rate calculation unit for calculating a natural frequency change rate based on the first natural frequency and the second natural frequency; and a determination unit for determining a damage degree of the industrialized structure based on the natural frequency change rate and the part of design elements.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
