STRUCTURAL DEFORMATION DETECTING DEVICE

摘要

A structural deformation detecting device comprises a vibration section provided with a plurality of vibrators for vibrating a structure serving as a measured object in a non-contact manner, a vibration measurement section configured to detect the vibration generated in the measured object at any measurement position in a non-contact manner, a housing on which the vibration section and the vibration measurement section are arranged at a specific interval, a time measurement section configured to measure the time elapsing till the vibration of the measured object caused by an optional vibrator is detected by the first vibration measurement section at a specific position, and a deformation determination section configured to determine whether or not there is a deformation by comparing the time taken for the transmission of vibration from the vibration position to the measurement position in a deformation-free state with the time measured by the time measurement section.
