Article Preview

A steel footbridge with a 27m net span, a worm-shaped curve and a vine bridge style was proposed to be constructed in Diexi city of Sichuan, China. Considering the appearance and the functional requirement, the bridge is designed as follows: the section outline is composed of 21 different ellipse-shaped transverse ribs with 1.5m spacing, and the transverse ribs are connected by 12 longitudinal ribs. Comparison between two optional structure schemes is carried out. Considering the mechanical performance and economy, the structure scheme, a truss structured system at lower part of the bridge, is adopted. Internal force analysis, member design and deformation calculation of the structure are accomplished. Finite elements analysis with ANSYS shows that the welded joints can meet the bearing capacity requirement. Connection between the bridge and the foundation platform is also presented in this paper.
