Discussion on the Flat Pull Pedestrian Suspension Bridge with Spatial Cable System in Tube Net Shape

In this paper, according to the requirements of wind resistance stability of super long-span flat pull suspension bridge, a new structure system of flat pull suspension bridge with tube- net-shape spatial cable system is proposed. The parallel cable system of traditional flat pull suspension bridge is improved to univalent hyperboloid disperse space cable system, to improve its torsional vibration frequency and torsional bending ratio. Combined with a 200 m pedestrian landscape suspension bridge in the gorge of Tibet, the project parameter design was carried out, the MIDAS finite element analysis model was established, and the dynamic modal analysis was carried out, to verify the superiority of wind resistance stability of flat pull pedestrian landscape suspension bridge with spatial cable system in tube net shape.
