Metrodome Roof Collapses Under More Than A Foot Of Snow

Metrodome Collapsed Snow
ESPN
UPDATE: The game is officially re-scheduled to be played in Detroit at Ford Field on Monday night at ET.

UPDATE: It seems that officials intentionally deflated the roof after two panels were damaged in the storm at around 5 mynewextsetup.us Sunday morning.

EARLIER:

The inflated roof of the Hubert H. Humphrey Metrodome in  Minneapolis has collapsed under the weight of a heavy snow storm.

The city has received over 17 inches of snow this weekend.

It's a good thing the Giants-Vikings games was already canceled today, because now there's nowhere left to play it.

It was originally rescheduled for Monday night, but now they will have to find a new location. The University of Minnesota Golden Gophers play football at TCF Bank Stadium, but it's not clear if that could be prepared for an NFL game in time, since it's also under more than a foot of snow. Also, the Giants did not bring cold weather gear, because they thought they would be playing inside.

The domed stadiums in Detroit and Indianapolis are also options, as are flipping it back into a home game for the Giants. Ford Field is the likely option as it has a game scheduled for Sunday, so it will already be set up, complete with FOX broadcast equipment.

The NFL will desperately want to get this game in on Monday, as there is no way to play a "make up" game before the end of the season. Also, most fantasy football leagues start their playoffs this week and rosters generally must be set by p.m. ET.

Some Las Vegas sports books have also taken the game off the board and canceled previous bets.

The roof has collapsed twice in and , shortly after the facility opened. It could take as much as a week to re-inflate.

The postponement of the game will also help Brett Favre to keep his consecutive games streak alive.

&#;&#;&#;&#;&#;&#;&#;&#;&#;&#;&#; In most failures, there is a reason for why that system or structure has failed. It is very rare for something to fail spontaneously. You can almost always find a cause of failure especially for engineered structures or systems. There is a positive to these causes of failure though. If we can understand these causes, we can make better designs for our structures and products. It shows that we can learn from our mistakes. A good example where we can analyze the causes of failure is the collapse of the Hubert H. Humphrey Metrodome, home of the Minnesota Vikings.

&#;&#;&#;&#;&#;&#;&#;&#;&#;&#;&#; The Metrodome is located in Minneapolis, Minnesota. It cost $68 million to build this domed stadium and it was opened in April of This dome with a capacity of 64, people wasn&#;t only home to the Vikings since the Twins (MLB) and the Minnesota Golden Gophers (NCAA football) regularly played there. It was the Timberwolves (NBA) home only for their first season. The Metro dome has been shut down since and is currently being demolished. A new stadium will be opened for the NFL season.

&#;&#;&#;&#;&#;&#;&#;&#;&#;&#;&#; The Metrodome had a roof with its outer layers made of a Teflon coated fiberglass fabric and an inner layer made of an acoustic fabric. The roof was able to support itself using air-pressure. For the inflatable roof to be successful, the internal pressure must be equal to or greater than the pressure outside of the dome. The space between the layers acted as insulation for the roof.

&#;&#;&#;&#;&#;&#;&#;&#;&#;&#;&#; There were a few incidents in the s that caused the roof of the Metrodome to rip or deflate (all due to weather and most due to snow) but these events weren&#;t as serious as the deflation. From December 10 &#; December 15, 17 inches of snow and strong winds led to the tearing and deflation of the Metrodome&#;s roof. Nobody was hurt but the Vikings did have to play two of their home games at another location. The roof needed to be replaced at an estimated cost of $18 million. The repairs and inflation were finished on July 13,

&#;&#;&#;&#;&#;&#;&#;&#;&#;&#;&#; Although no one was hurt, the Vikings organization still took a hit financially. They lost two weeks of ticket sales (including concessions and merchandise sales in the stadium) and repairing the roof decreased their funds by approximately $18 million.

&#;&#;&#;&#;&#;&#;&#;&#;&#;&#;&#; We can clearly see that the major/ most important cause of the roof&#;s deflation was Mother Nature. The storm brought an accumulation of 17 inches of snow and heavy winds, which was too much for the dome to handle. Another cause for this failure can be poor planning and a poor design. It&#;s a bad idea to come up with a design to have a pressurized dome in a region that experiences heavy snow accumulations and strong storms. It is just asking for failure. Also, a company named Birdair inspected the roof in April of Their report said that the outer membrane was in good condition but the inner liner was in fair to poor shape. The inner line was dirty and had small holes in it that were to be monitored. On the contrary, the Metropolitan Sports Facilities Commission staff said the roof was fine and wanted to test it again in four more years. Mind you, this was the same roof from (28 years old). This is another large cause of the problem.

&#;&#;&#;&#;&#;&#;&#;&#;&#;&#;&#; The strategy for when snow was expected was to pump hot air between the roof&#;s two layers. Workers would also use steam and high-powered hot water hoses to melt the snow off of the roof. These protocols were followed since the temperature inside of the dome when the roof collapsed was about 80&#; F and therefore failure to prevent the collapse can be ruled out as a cause.

&#;&#;&#;&#;&#;&#;&#;&#;&#;&#;&#; The Metrodome&#;s short year lifespan has come to an end and a new stadium should be ope
n in It is very possible that the failures of the Metrodome have led to an improved design for the new stadium. It looks like the new Minnesota Vikings stadium will still have a roof but one that is fixed and structurally supported using trusses. The poor design and bad location for a pressurized dome mixed with an old roof and extreme weather conditions created a recipe for disaster.

A Look At The Vikings Stadium&#;s Space-Age Roof

MINNEAPOLIS (WCCO) — The most striking feature on the iconic U.S. Bank Stadium in downtown Minneapolis is something you look right through — literally.

Instead of a s-style retractable roof, which most NFL stadiums rarely open, the Minnesota Vikings are using a revolutionary design that is incredibly light.

“It’s truly going to feel like you’re at, you know, an open-air stadium, but you’ll be here in the winter months,” Mortenson Construction’s Brendan Moore said.

The colossal stadium is million square feet. The entire old Metrodome could fit inside it.

And 60 percent of the slanted roof is covered with a product called ethylene tetrafluoroethylene, better known by the nickname ETFE.

Casey Ramsey, of German firm Vector Foiltec, led more than a dozen workers in installing the special roof panels 30 stories above the ground.

There are 75 separate sections, manufactured by Vector Foiltec, with each one measuring by feet, and weighing 1, pounds.

“Approximately 14 people, all with fall protection and safety rope training, they work together to pull the piece in one piece all the way down and snap it into place,” Ramsey said.

ETFE was developed in the s by DuPont for insulation on wires and cables. It is 1/of-an-inch thick and a fraction of the weight of glass. Three gently-inflated plastic layers give it flexibility and durability.

And like its cousin, Teflon, ETFE has chemical properties allowing rain and snow to slide right off.

“And there’s nothing like it, literally, in the world,” Michele Kelm-Helgen, chair of the Minnesota Sports Facility Authority, said.

She says using ETFE reduced the steel load on the stadium roof by 1, tons. That is equal to six Boeing aircraft.

Unlike the Metrodome, this roof will not collapse from the weight of snow and ice.

“That steep roof will allow it to shed the snow, and it will come down to these snow gutters, and there is a melt system within these snow gutters that we will use,” Kelm-Helgen said.

ETFE is already popular in stadium design around the world. The Olympics Water Cube in Beijing is made of it. And ETFE gave Munich’s Allianz Arena its shape-shifting appearance.

Minnesota’s ETFE roof will not be lighted, but the spaces around it will, giving it a glow of changing colors — including Vikings purple.

The ,square feet of roof sits atop story glass doors facing downtown Minneapolis, which will open and close.

ETFE provides a warming thermal effect in harsh weather, in what stadium builders say is an overall “feel.”

“Having an ETFE roof will allow the fans to benefit from the comfort of an indoor environment, while still having an open-air feel year round,” Ramsey said.

Now that the outside roof and walls are mostly complete, workers will concentrate on the inside of the stadium during the winter. It should open next summer in time for the NFL season.

On December 12,the much-maligned Metrodome finally gave out. After nearly a foot and a half of snow accumulated on top of the home of the Vikings stadium roof collapse Minnesota Vikings, the roof caved in spectacular fashion, dumping truckloads of powder upon the football field.

The collapse left the Vikings out in the cold. The team eventually vikings stadium roof collapse get its wish as the city of Minneapolis approved a new stadium to be built in the same spot. But while construction crews razed the defunct Metrodome and built the Vikes' new billion-dollar home, the team played outdoors at nearby TCF Bank Stadium on the campus of the University of Minnesota, where gametime temperatures dropped to -4 degrees Fahrenheit for this month's playoff matchup against Seattle.

The roof, then, has a sort of history when it comes to Minneapolis stadiums. The new home of the Vikings (and host of Super Bowl LII), U.S. Bank Stadium, does something altogether new in North America. Its designers brought the best of the outside in, all while keeping U.S. Bank Stadium a fully indoor venue.

Minnesota Vikings

The Roof

The Metrodome was a marvel when it opened in Air once supported the fiberglass fabric roof—though that air couldn't stand up to the power of snow in Minnesota. In the decades since then, the plethora of new, crazy-expensive stadiums built in America has included many with retractable rooves: those that can slide open when the sun shines and close the lid when the rain comes.

This content is imported from YouTube. You may be able to find the same content in another format, or you may be able to find more information, at their web site.

But the Vikings are trying something else. "The only reason to have a retractable roof was because others had one," tricare prime login Bryan Trubey, HKS architect and designer of the building. Instead, Trubey helped design a stadium that, he says, "felt like outdoors all the time."

The key is ETFE, a space-age, plastic-like material used in construction for roughly 30 years. ETFE is lighter and stronger than traditional roofing materials. It's also translucent—so much so that a stadium in New Zealand with a roof made of this stuff can grow natural grass indoors.

Each of the ETFE panels in the Vikings' roof is made of three layers of Vikings stadium roof collapse foil, welded into panels with edges captured into aluminum frames, which are themselves connected to the steel brackets of the roof structure. Each panel has a series of air supply units that, while not structural, helps the "pillows" stabilize the foil, according to engineering firm Thornton Tomasetti. The air units do not run constantly or create airflow, but simply maintain a minimum pressure within each panel.

The outer layer of ETFE foil is printed with a silver ink to create a "frit" that helps reduce the heat of the sun on the roof surface and deflect the sun, while the inner layer of air helps maintain the desired temperature, altogether controlling the thermal needs of the 66,seat building. About 60 percent of the roof is clad in these translucent ETFE pillows, amounting to a total ofsquare feet, while the remainder is a traditional steel deck and membrane roof.

"We arrived on the ideal solution for this market, that indoor-outdoor experience," says Lester Bagley, executive vice president of stadium development for the Vikings. "A stadium for all seasons."

More than just bringing the light in, ETFE also ensures the snow will stay out. The lightweight but strong material allowed designers to run a superspan that includes a single foot-long single ridge truss the entire length of the field. It's set asymmetrically to allow for the sunnier south side of the building to use more ETFE than the north side. The roof that sits over the million square foot stadium is one of the lightest stadium roofs in the world, despite its snow load requirements. The roof is so minimal that the Vikings can still do a flyover before the game. In an indoor venue.

The steep pitch of the roof () fits the Northern European design motif and serves a practical purpose of helping snow slide into a snow gutter that rings the top of the building. This gutter has a melting system within to take the cascading snow and turn it into full liquid before the weight becomes a Metrodome-type issue.

The Doors

Minnesota Vikings

Minneapolis has its long, cold winters, but that doesn't mean that football in September is frigid. The Vikings wanted to welcome the warm air, not just shun the cold, and that's where the idea for huge glass doors started. The west end of the building features the five largest pivoting glass doors in the world, 55 feet wide and ranging from 95 feet to 75 feet tall. With all these translucent and transparent materials, even on a cloudy day in Minneapolis enough natural light streams into the building that the new stadium looks like it opens to the outside.

Located at the west entrance, where the Vikings expect roughly 70 percent of fans to enter, the five large doors can remain open during contests, bringing natural air into the stadium. For vikings stadium roof collapse cold winters, though, much smaller regular-sized entrance doors embedded columbia bank home the glass can open instead, keeping the frigid temperatures where they belong: outside.

The Tennessee-built doors made from 30, square feet of glass from Owatonna, Minnesota, rotate on hydraulic pistons. The curtain of glass also breaks up the usa phone code from india black zinc metal panels that will eventually wear into a weathered gray. vikings stadium roof collapse Build

Minnesota Vikings

Eric Grenz, construction executive for Mortenson Construction, sayscubic yards of concrete were used in the construction of the building. The highest point of concrete rose feet on the ring beam, taller than the Statue of Liberty. To keep the project on track, Mortenson needed to conduct year-round concrete pours. And year-round means workers pour concrete even in degree temperatures, requiring heated cement trucks and heated forms that can properly cure the concrete.

Incredibly intricate logistics at the downtown site that sometimes had Mortenson managing a dozen cranes inside the bowl. "We had a 4D schedule, an animation of the entire sequencing of the job as a whole," Grenz says. "It really helped to understand the flow."

Minnesota Vikings

Besides Viking football games, Minneapolis' newest megastructure is already slated to host the Super Bowl in and the NCAA men's basketball Final Four in So plenty of fans will get to gaze up at the new vision for a colossal roof, one that feels like it's hardly even there.

MINNEAPOLIS, MN — On Saturday, Dec. 11, the Minneapolis-Saint Paul metro area was pounded with more than 17 inches of snow. Inside the walls of the Hubert H. Humphrey Metrodome — which no longer stands today except in the memories of Minnesota sports fans — a Fox news crew was setting up cameras for the Vikings' Monday matchup against the New York Giants. The game was originally scheduled for Sunday, but it was postponed due to concerns about the roof.

The Fox crew noticed water leaking from the roof and decided to leave their cameras on throughout the night. In the early hours of Dec. 12, the weight of the snow punctured a massive hole in the nearly year-old teflon roof, causing an avalanche onto the field. No one was injured.

The day before the collapse, Metrodome crews hosed hot water on the roof to melt the snow. But low temperatures turned that water into chase private client banker careers, Roy Terwilliger, the chairman of the Metropolitan Sports Facilities Commission at the time, told the Star Tribune.

EARLIER:

The inflated roof of the Hubert H. Humphrey Metrodome in  Minneapolis has collapsed under the weight of a heavy snow storm.

The city has received over 17 inches of snow this weekend.

It's a good thing the Giants-Vikings games was already canceled today, because now there's nowhere left to play it.

It was originally rescheduled for Monday night, but now they will have to find a new location. The University of Minnesota Golden Gophers play football at TCF Bank Stadium, but it's not clear vikings stadium roof collapse that could be prepared for an NFL game in time, since it's also under more than a foot of snow. Also, the Giants did not bring cold weather gear, because they thought they would be playing inside.

The domed stadiums in Detroit and Indianapolis are also options, as are flipping it back into a home game for the Giants. Ford Field is the likely option as it has a game scheduled for Sunday, so it will already be set up, complete with FOX broadcast equipment.

The NFL will desperately want to get this game in on Monday, as there is no way to play a "make up" game before the end of the season. Also, most fantasy football leagues start their playoffs this week and rosters generally must be set by p.m. ET.

Some Las Vegas sports books have also taken the game off the board and canceled previous bets.

The roof has collapsed twice in andshortly after the facility opened. It could take as much as a week to re-inflate.

The postponement of the game will also help Brett Favre to keep his consecutive games streak alive.
