Apparatus and Method for Monitoring Damage of Structure with Measuring Strain and Digital Twin

摘要

In order to monitor structural stability and damage of structures such as bridges, the present invention installs a strain measurement device capable of measuring strain at a plurality of measurement points on a target structure, and uses the initial strain measured at a plurality of measurement points. , A hypothetical structural analysis model that shows the response characteristics of the target structure when a load is applied to the target structure, that is, the structural behavior and structural response of the structure identical to that of the target structure when a load is applied (digital twin). ) Is formed, the strain is measured at a desired time interval for a desired time through a strain measurement device, and applied to a virtual structural analysis model that has been built in advance, thereby determining and monitoring the damage of the target structure. It relates to a "damage monitoring method" and a "damage monitoring device of a structure" operated by this monitoring method.
