| Abstract: | This paper analyzed the structural stress and structural stability of the Zhangjiagang large-span cable-stayed bridge which is located in Changde,Hunan by using the finite element software MIDAS.Based on the structural calculation and analysis model,we get the stress distribution of bridge in the limit state and the seismic bearing capacity of bridge.The analysis data all meet the standard requirements.The analysis results of this paper provide important basis for the daily operation and safety assessment of the bridge. |
