| A 3-span continuous girder bridge supported by rubber bearings to disperse seismic lateral forces was affected by 2007 Niigata-ken Chuetsu-oki earthquake. The bridge pier columns and abutment walls were not damaged. However, all pier and abutment foundations moved with the ground displacement and some cracks were found at the pile heads of both abutments. This paper presents the preliminary damage analyses of the bridge to simulate the effect of the earthquake. |
