Retractable roof stadiums have ushered in a new era in the evolution of sports stadiums around the world. The high cost of new stadiums demands that they be more versatile and not just used on game days. They need to be both open air and enclosed for a wide range of venues. That means stadiums with retractable roofs.
This presentation will address the structural engineering challenges that go into the design and construction of this new genre of building type – the retractable roof stadium and ballpark. Featured will be the new Reliant Stadium – home of the NFL Houston Texans and the Houston Livestock Show and Rodeo, Minute Maid Park – the home of the Houston Astros, and Cardinals Stadium – home of the NFL Arizona Cardinals.
With spans typically ranging from 150 to 250 metres or more, these “long span” roof structures with moving roofs present a host of challenges. What type of steel is used to keep the weight down, how are the steel truss connections made, how are the roofs erected and what role does this play in the structural engineering design, how are the roofs operated for potential thunderstorm and hurricane wind conditions, what happens if a mechanization failure occurs and how is this accommodated in the structural design, how are natural turf fields accommodated in the operation and maintenance of the building – all these types of questions will be addressed in this presentation.
