| Abstract: | The steel-tube node of the bridge pylon for the highway and railway color needle-shaped pylon cable-stayed bridge is stressed complexly.The article fully understands the stress distribution status of steel pylon node and the stress centralizing extent at the structure detail through the finite element analysis of steel tube structure of Tuanpo steel pylon.On this basis,the design method of fatigue is further considered.The measures are taken in the design to enhance the fatigue resistant performance of structure to be referred for the same structures of the future. |
