[V-210] Damage detection using rate of change of infuluence line of deflection by optical measurement method
Keywords:3D measurement, FEM analysis, Natural frequency, Deflection influence
In recent years, aging and lack of maintenance of bridge structures constructed during the period of high economic growth
It is necessary to have an efficient and effective maintenance method. Local public bodies in particular
There are many design bridges for the small and medium-sized bridges, and there are many bridges of unknown construction age. these
Design documents using a 3D laser scanner for bridges in the city, and if it is possible to identify the location of damage by calculating the rate of change of the influence line of deflection, it can be expected to simplify and quantify maintenance and management. Conceivable.
