The subject of the tests is the dynamic response characteristics of Katashina-gawa Bridge in Kan-etsu Expressway and of a continuous girder bridge in Metropolitan Expressway during earthquakes. Katashina-gawa Bridge is a curved truss bridge with high piers (R=2,200 m, H sub max = 69m). Its dynamic response characteristics by longitudinal, transverse, and oblique direction excitations, effects of a curve, and a distribution of stress in its suprstructure were investigated by vibration tests of its model. Analytic modeling in the dynamic analysis of Katashina-gawa Bridge was also examined. The continuous girder bridge has a superstructure connected with piers by hinges through twelve spans. Its dynamic response characteristics by longitudinal and transverse direction excitations were investigated and are compared with those of a simple girder bridge and a continuous girder bridge with dampers by vibration tests of their models. Analytic modeling in the dynamic analysis of the continuous girder bridge was also examined. (Author)Read More
