Title:
STRUCTURE BENDING MEASUREMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/183549
Kind Code:
A1
Abstract:
This invention comprises a bending acquisition means for acquiring the amount of bending produced in an area under measurement on a structure by a vehicle traveling over the structure, a vehicle position acquisition means for acquiring the position of the vehicle on the structure at the time at which the bending amount was acquired, and a stiffness coefficient calculation means for calculating a stiffness coefficient specifying the relationship between the magnitude of the force applied to the structure as a result of the weight of the vehicle and the bending stiffness of the structure on the basis of: a relational expression between the position of the vehicle on the structure, the magnitude of the force, the position of the area under measurement on the structure, the length of the structure, the bending stiffness, and the amount of bending produced in the area under measurement; the acquired amount of bending; and the position of the detected vehicle.
