No One Saw This Coming? John Podhoretz at Commentary wonders. Awesome Video! Andy Hutchins at SB Nation doesn't hold back. This video is like watching the Hindenburg blow up in real time--then dump tons of snow onto a field where Brett Favre plays football.
In a year with a lot of great moments, this may be the single most memorable thing to happen in the world of sports in Even something like the Metrodome--considered outdated, a tenement to be fled--is a modern kind of miracle, with its Teflon-and-fiberglass roof held aloft by nothing more than circulated air and willpower.
Someone dreamed that up, and then we built it. It's really an incredible thing. And yet here is the painful-seeming truth Nearly everything we build--nearly everything you saw on your way to work this morning, the roof that will be over your head when you go home tonight--will one day be gone.
Teddy Partridge at Firedoglake takes the opportunity to indict the entire species:. Bridges fall down, culverts wear out, roofs collapse. I went to a concert at B. Place once, which had the same type of inflated roof. One the way out, there were several regular doors propped fully open. Got a nice tailwind on the way through. Just a few feet away, though, everything felt normal. I just got the impression they opened them after the event because everyone is leaving at the same time.
Metrodome Roof - Constant Inflation Since ? Factual Questions. You must have forgotten about the collapse of the roof in Sounds like they are pretty much gone now. Interesting article - thanks! Anecdote about the doors at the Metrodome: In order to keep the air pressure higher inside the dome and, thus, keep the dome inflated , the Metrodome used revolving doors for all of the exits. Inflatable roofs are usually dome-shaped, because that provides the optimum amount of volume for the pressurized air to maintain shape.
The roof fabric is pliable, usually made of tensile fiberglass or polyester, hemispherical, and attached at the foundation with heavy weights. Inflation fans, located just under the roof, keep the dome inflated and blow into a common duct that circumnavigates the building. The air is then funneled into the interior arena from that duct.
Inflatable dome-roofed structures remain stable as long as the stadium's internal air pressure equals or exceeds outside forces such as those exerted by wind, snow or even earthquakes. All such systems rely on two types of exit doors on the ground level and a revolving door that can be used to help moderate pressure. Pete Sala, managing director of the 2. And the Metrodome is currently the only active air-pressurized stadium in the National Football League.
The former residents of the Silverdome, the Detroit Lions, have played at Ford Field since that facility opened in The Silverdome is now used for music and various sports events. The University of Northern Iowa U. Another air dome, Vancouver's BC Place , where the opening ceremonies of the Winter Olympics were held, is being replaced with a retractable fabric roof. Sala says the stadium was built about the same time as the Carrier, which opened in September Dome was part of our generation—it's part hybrid now," he notes.
But the Carrier Dome is here to stay. It's always been properly inspected and maintained, Sala says, pointing out that Syracuse gets more snow than Minneapolis. Further, the Carrier roof has held up even with as much as 1.
What worked in The technology behind air-pressurized domes was popularized by the late architect and engineer David Geiger, who designed the U. Pavilion for Expo 70 in Osaka, Japan; but inflatable domes predate Geiger. The U. Bary for an inflatable structure. It's a technology, though, that even Geiger may have foreseen as obsolete. His own designs graduated to an unpressurized cable-dome structure, as evidenced by his work on the roof of the Florida Suncoast Dome—now called Tropicana Field—in Saint Petersburg, for example.
