Millennium Park BP Pedestrian Crossing, Chicago, USA

The structural engineering design and constructive aspects of a unique stainless steel-clad pedestrian crossing at the Millennium Park in Chicago are presented. The overall bridge form is characteristic of architect Frank O. Gehry’s work: metallic surfaces freely flowing in profile and serpentine in plan. Details of the computer aided steelwork detailing, fabrication, and erection are presented. Substantive engineering analysis and design details including the issue of synchronous pedestrian walking vibrations are summarised. H.
