Design and Construction of Catwalk System of Suspension Bridge of Runyang Bridge

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 accelerate 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 vibration of the catwalks under live loading. In this paper, the design and construction of the catwalk system of the Bridge are systematically described.
