NON-CONTACT MEASUREMENT METHOD AND DEVICE OF DYNAMIC DEFLECTION OF PC GIRDER

摘要

PROBLEM TO BE SOLVED: To provide a non-contact measurement method and device of dynamic deflection of a PC girder that can measure the dynamic deflection of the PC girder using one or a plurality of sensors capable of performing easy and accurate measurement.SOLUTION: In the non-contact measurement method of dynamic deflection of a PC girder, when an error of the vertical deflection of the PC girder having undergone horizontal displacement is corrected, the horizontal displacement of the PC girder 21 is measured by a movable bearing section 43, the deflection of the PC girder 21 is detected by non-contact sensors 31 and 32, and the deflection is corrected using the measurement result and an error table for correcting the error.
