Downward Through-pass Cable-Stayed-Arch Composite Structural System Bridge: Yanluo Pedestrian Bridge in Shenzhen

Abstract

The Yanluo Pedestrian Bridge has a length of 136.0 meters, a width of 11.5 meters, a main span of 108.0 meters, and a rise span ratio of 1/11.74. The bridge design introduces the innovative "Downward Through-pass Cable-stayed Inclined Arch Composite Structural System." Compared to conventional deck-type arch bridges, this composite structural system significantly enhances the load-bearing capacity of the main arch, reduces the horizontal forces on the arch abutments, and improves the stiffness of the main arch. The Yanluo Pedestrian Bridge consists of the main arch, main girder, bridge towers, main cables, back cables, vertical braces, steel pipe columns, and foundations. The construction employs minimal support in the water.
