V&A Waterfront Swingbridge (Overall Winner/ Bridge Category Winner) - SAISC Steel Awards 2020

The new replacement swing bridge, V&A Waterfront is nominated for Steel Awards 2020. https://www.saisc.co.za/project/the-n... ⁠ The new replacement swing bridge in the V&A Waterfront is an aesthetically pleasing and functional structure in Africa’s oldest working harbour. ⁠ ⁠ The V&A already had a swing bridge that was well-used and well-loved. It was an efficient structure that opened and closed up to 60 times a day, carrying up to 2.4 million people per year. It was, however, 22 years old: a lifetime in the context of the V&A. The 2 m wide walkway, which once seemed appropriate, could no longer cope with the rising numbers of pedestrians.⁠ ⁠ The new swing bridge has a span of 40 m. The deck is cable-stayed with a single plane of 4 locked coil cables connecting to a central, upstand spine beam. The spine beam is a 500 mm wide fabricated box with a total depth of 800 mm, but only 470 mm protrudes above the top of the deck. The reclining pylon is in the same plane as the main central beam and its stiffness transfers the cable loads into the piled substructure. The steel with timber deck is rotated on a slewing bearing, which is stressed down onto a doughnut-shaped pile cap by 34 vertical Freyssibars.⁠ ⁠ #SAISCSteel2020 #SeeYourselfInSteel #Architecture #Steel #StructuralEngineering
