Engineering Considerations for a Floating Swing Bridge in the Port of Osaka

摘要

The world's first swing and floating arch bridge is going to appear in the Port of Osaka in the year of 2000. It is a highway double-rib arch bridge accommodated with 6 traffic lanes connecting two reclaimed islands and rests on two hollow steel floating foundations. It is supported horizontally by dolphins and rubber fenders and once in a while can swing around a pivot near an end of the girder after the pivot is inserted and a part of transitional side bridges is jacked up. Comprehensive research works have been conducted including large-scale experiments, simulations and numerical analysis.
