Stadium La Montura, Chile
A roof made of steel and fabric membranes was designed for the soccer stadium in San Bernardo, a city in the south of Santiago. The elegant, curved design in lightweight construction now also covers the standing area.

The main structural elements, such as arches and bracing curve members, are made of steel and have a total span of ~ 241.1 ft between the concrete pile supports. The cladding system consists of a series of tensioned fabric membranes with a width of ~ 10.5 ft, which span a length of ~ 23 to 42.7 ft and are surrounded by corner cables.
This roofing system creates a transparent picture of the roof while protecting spectators from the effects of the weather.

Plate girder is an economical choice for long spans construction. I-section steel plate girder typically has a deep web to maximize its shear capacity and flange separation, yet thin web to minimize the self-weight. Due to its large height-to-thickness (h/tw) ratio, transverse stiffeners may be required to stiffen the slender web.
