| Abstract: |
The three-pylon multi-span suspension structure is one of the proper structure types for continuous large spans crossing rivers and straits. Based on the design of Taizhou Bridge, stiffness selection for the middle pylon is introduced in this paper. In order to solve the design difficulty of three-pylon multi-span suspension bridge, the multi-scale elastic-plasticity stability analysis and the study on the anti-slippage safety between the cable saddle on the middle steel pylon and the main cable are carried out, which have been presented in this paper. The key design technology for the middle pylon of three-pylon multi-span suspension bridges would provide the powerful support to the design of the middle steel pylon structure. |
