Abstract : In the previous construction of long span suspension bridges at home and abroad , the
storm strands were often used for catwalks to improve their wind stability. However , in order to accel
erate the construction and reduce the cost of the Suspension Bridge of Runyang Bridge , the global wind
stability of catwalks of the Bridge is achieved by adjusting the spacing and numbers of cross bridges
connecting the catwalks , and the horizontal and vertical dampers are also added to mitigate the vibra
tion of the catwalks under live loading. In this paper , the design and construction of the catwalk sys
tem of the Bridge are systematically described.
Key words : suspension bridge ; catwalk ; design ; construction
