| Abstract: | A constructing rail transit bridge with U-shaped girder in a place of China is regarded as the engineering background of this paper. The seismic performance and train running characteristics of U-shaped girder bridge,which may be with or without seismic isolation device,are discussed synthetically. The result of the research shows that the seismic performance of rail transit U-shaped girder viaduct with seismic isolation device is improved obviously and the train running characteristics of the bridge is also ensured. |
