TWO-STORY SUSPENSION PDEDSTRIAN BRIDGE WITH IMPROVED PERFORMANCE AGAINST WIND FORCE

摘要

The present invention relates to a sidewalk suspension bridge, comprising: a main cable connecting a first position and a second position spaced apart from each other; A lower deck girder having a lower passage through which pedestrians pass; An upper hanger cable connecting the lower bottom plate girder and the main cable; An upper deck girder having an upper passage through which pedestrians pass; A first upper hanger cable connecting a plurality of transverse ends of the upper floor plate girder and the first main cable along a longitudinal direction, and the other transverse end of the upper floor plate girder and the second main cable in a longitudinal direction An upper hanger cable including a second upper hanger cable for connecting a plurality of lines along the line; Consisting of a connecting cable that connects a plurality of upper deck girders and the lower deck girders along the longitudinal direction, the connecting cable acts as a wind cable for the upper deck girder to prevent displacement of the upper deck girder. In addition, for the lower deck girder, the connecting cable acts as an X-shaped restraint cable to suppress the fall due to wind load, providing a sidewalk suspension bridge that ensures the safety of pedestrians more reliably.
