Study of 500-Meter Hyperbolic Parabolic Space Cable Pedestrian Suspension Bridge

This paper proposes a hyperbolic parabolic space cable pedestrian suspension bridge structure system based on the egg-shaped arched tower based on the wind resistance requirements of a super-long-span pedestrian suspension bridge. Parallel cables bear vertical loads, and two sets of cable systems of hyperbolic parabolic carbon fiber space cables and wind-resistant cables improve torsional stiffness, work together, complement each other, and significantly increase space rigidity. It can fundamentally solve the problem of wind stability of extra-long-span pedestrian suspension bridges, and can build 500-meter-long super-span pedestrian suspension bridges.
