| Kitago viaduct is the bridge of the steel-concrete mixed structure that it is planned in Sapporo. The characteristic is the frictional power between the steel-concrete is expected the transmission of the shear and a deviation stop such as studs and PBL isn’t installed in the surface of the junction and the steel shell cell.Though it can work for the improvement in the simplification of the junction structure and the execution、 there are few studies on the frictional force in the junction、 so we conducted FEM analysis and experiments to verify the validity of this structure.It is reported about the fatigue and destruction experiment by the reduction specimen of the actual bridge junction. |
