Abstract
<p> Two span continuous steel cable-stayed bridge “Kuwazuru Ohashi” was damaged by the 2016 Kumamoto earthquake, displacing whole girder, uplifting a girder end, twisting cables, inclining main tower, and so on. This paper proposes restoration of the bridge, replace of cables and displace of the girder utilizing monitoring, improvement of a bearing to redundant structure in order not to be damaged easily in the future. In addition, this paper proposed the method to estimate structural state change utilizing data due to tensile force and eigenfrequency to maintain the bridge after restoration.</p>
