Abstract According to the demand of 800m super long-span pedestrian suspension bridge in 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 the both sides of the hillside, and the bridge tower structure is cancelled to save the cost; The univalent hyperboloid tube-network space cable system provides horizontal component, greatly improves the lateral stiffness and torsional stiffness of pedestrian suspension bridge, and has good space structure stiffness. Combined with a 800m super long-span pedestrian suspension bridge project in 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.
