Wind and Pedestrian Vibration Assessment on the New Swan River Pedestrian Bridge

The paper presents the problems related to wind and pedestrian induced vibration that have been faced during the design of the Swan River Pedestrian Bridge (SRPB) in Perth (Australia).

It is a three-span arch structure (approximately 80-140-80 m length, respectively). Arches are made by lattice steel structures and the deck is suspended to the arches by sub-vertical strands. Each span has two crossed arches with triangular cross-sections that vary dimensions along the arch. Two cantilever extensions are connected to the crown of the central arch. Arches are supported by quite flexible piles.
