Design of 800-m Hillside-Anchored Pedestrian Suspension Bridge with Univalent Hyperboloid Space Cable Net

Abstract

According to the demand of 800-m superlong-span pedestrian suspension bridge in a mountain scenic spot, a hillside-anchored univalent hyperboloid spatial suspension network pedestrian suspension bridge is proposed. The univalent hyperboloid tube–network space cables are dispersed and anchored on both sides of the hillside, and the bridge tower structure is removed to save cost. The univalent hyperboloid tube–network space cable system provides a horizontal component, greatly improves the lateral stiffness and torsional stiffness of pedestrian suspension bridge, and has good space–structure stiffness. Combined with an 800-m superlong-span pedestrian suspension bridge project in a mountain scenic spot, the static and dynamic stress characteristics of MIDAS finite-element are carried out to verify the rationality of the pedestrian suspension bridge with hillside-anchored spatial cable system and its good wind stability.
