PTFE fabric tensile platform canopies

Alternating V-shaped PTFE coated glass fibre fabric canopies were installed at three platforms at the Maracana metro station ahead of the 2014 Fifa World Cup.  Each platform has a 121m long canopy run, with an additional 22.5m long standalone canopy.  All three platforms total in excess of 3000 square metres (surface area) of fabric.  Standardisation of the bay geometries, where possible, were key to keeping design and fabrication costs to a minimum.  Rainwater drainage detailing was also critical to the design, with large hoppers at column locations incorporating a siphonic drainage system.  THD was responsible for the design, engineering and coordination of the fabric and fittings to the steel frame while Tensys performed the membrane analysis.
