The strain visualization device is a strain measurement sensor developed for long-term monitoring of infrastructure. Since the strain detection position of the strain visualization device is structurally separated from the member surface, the distance from the neutral axis is larger than that of the member surface, and the strain value is large when strain measurement of members with bending deformation. Therefore, while showing the correction method, it was experimentally verified that the strain visualization device can be applied to strain measurement of members with bending deformation by adding the correction. In addition, the strain visualization device was applied to strain measurement of the loading test of an actual bridge, and its applicability to an actual structure with bending deformation was proved.
