Denver International Airport Fabric Roof Design
The design of Denver's Landside Terminal Complex for the new Denver International Airport, called for some far reaching vision coupled with imaginative building technologies. Because of...
Tensile Terminal
Few can miss a fabric roof that covers a 1.45 million sq ft area. The one covering the Denver International Airport's Landside Terminal complex (reportedly the nation's...
Drifted Snow on Roofs
Drift snow loads on multilevel roofs account for about 75 percent of all snow load related roof collapses. A case history of snow drifts provides the foundation for a discussion of the...
Hugo 1989 - The Performance of Structures in the Wind
The performance of buildings in the Carolinas during Hurricane Hugo, 21-22 September 1989, is reviewed. Wind speeds in most locations were below the design levels specified in the local...
Lessons Learned by a Roof Consultant
Hurricane Hugo left in its wake, extensive damage, an estimated $6 Billion loss. It is estimated that over 80% of the losses were related to roof failures, and the associated water damages....
Masonry Performance in the Coastal Zone
Investigators from the National Concrete Masonry Association (NCMA) surveyed the coastal areas of South Carolina from Charleston to Myrtle Beach during a seven day period just after hurricane...
Roof Wind Damage Mitigation: Lessons From Hugo
Hurricane Hugo caused extensive roof damage in Charleston, South Carolina and surrounding areas. Extensive field investigations have revealed the causes of many of the problems. This paper...
Floating Fabric Over Georgia Dome
The 400,000 sq ft free-span roof cover the new $210 million Georgia Dome may look as festive as a circus tent. But next fall, when the 70,500-seat arena becomes the home of the Atlanta...
Designing in Circles
Round buildings are a popular�but sometimes expensively perceived�design choice. With careful engineering and planning, they can offer a creative, cost-competitive option. They add another...
Toronto Skydome Retractable Roof Stadium?The Roof Concept and Design
The Toronto SkyDome is a first of its kind sports stadium with a retractable roof which results in, essentially, a fully open air stadium with the roof fully retracted. This unique roof,...
