Keywords:Natural Vibration Mode, Damage Evaluation

A method for quantitatively evaluating the repair effect has not been established.
The authors are focusing on the appearance of vibration modes as a method of evaluating structural performance.
In the past, there were no reports of vibration mode measurement results for bridges with simple repair of concrete slabs.
This paper reports on the vibration modes of a two-span continuous steel I-girder bridge with temporary repairs to the concrete slab.
