Designing another Australian-first: a 100 metre stress ribbon pedestrian bridge that is only 450 millimetres thick, yet robust enough to meet demanding accessibility, wind and loading conditions.
Projects like this remind us that elegance only matters when it is backed by rigorous performance. In this case, the bridge’s visual lightness is matched by rigorous engineering to accommodate heavy loading, withstand wind, and provide inclusive access for all users.
This is the first post in a three part series on this bridge: how the 100 metre stress ribbon span was realised, how its structural behaviour differs from conventional pedestrian bridges, and how a bespoke finite element modelling approach, developed by BG&E bridge engineer Bruce Gibbens, was used to capture its performance over time.
Follow along as we explore how the bridge works and how we tested it in the next posts.
