Brunel Trusses and a moving Field in this Desert Wonder
University of Phoenix Stadium
Glendale, Arizona
Our award-winning structural engineering services for the $425-million University of Phoenix Stadium, new home of the Arizona Cardinals and the Fiesta Bowl, leverage two unique structural systems – a 500,000-square-foot retractable roof and the first U.S. operable playing field – to set the standard for a modern multipurpose facility.
The main roof was assembled on the stadium floor and jacked into place using an innovative single 5500-ton lift. Two 87-foot deep Brunel trusses span 700-feet between concrete super columns to form the primary roof structure.
The Brunel trusses support two 180 ft. long x 270 ft. wide fabric clad retractable roof panels that bipart from mid-field to expose the entire field. A unique Vierendeel-lenticular grid truss system was developed for the retractable panels to maximize light transmission into the building and minimize visual clutter from the steel framing.
