  1. The folks in the Superdome are heading to the Astrodome. I'm a little puzzled by the statement in bold...

     

    NEW ORLEANS - At least 25,000 of Hurricane Katrina's refugees, a majority of them at the New Orleans Superdome, will travel in a bus convoy to Houston and will be sheltered at the Astrodome, which hasn't been used for professional sporting events in years.

    Evacuees with special problems already have been evacuated to hospitals in other Louisiana cities, but the 23,000 people now confined to the stuffy, smelly Superdome, as well as some other refugees will go to Houston, about 350 miles away.

     

    The marathon bus convoy should take two days, officials said.

     

    "Our view is the move to the Astrodome is temporary," said William Lokey, chief coordinator for the

    Federal Emergency Management Agency. "We're buying time until we can figure something out."

     

    Ann Williamson, secretary of the Louisiana Department of Social Services who is working on the evacuation plans, said, "The remarkable offer from Texas did not have an end date."

     

    FEMA will provide 475 buses for the transfer, and the Astrodome's schedule has been cleared through December for housing evacuees, said Kathy Walt, a spokeswoman for Texas Gov. Rick Perry.

     

     

    I didn't realize the Astrodome was still being used? :doh:

  2. What's the latest on the levee repair? Anyone hear anything?

    424404[/snapback]

    To repair damage to one of the levees holding back Lake Pontchartrain, the Army Corps of Engineers said it planned to use heavy-duty Chinook helicopters to drop 3,000-pound sandbags Wednesday into the 500-foot gap in the failed floodwall. But the agency was having trouble getting the sandbags and dozens of 15-foot highway barriers to the site because the city's waterways were blocked by loose barges, boats and large debris.

     

    Officials said they were also looking at a more audacious plan: finding a barge to plug the 500-foot hole.

     

    It could take close to a month to get the water out of the city. If the water rises a few feet higher, it could also wipe out the water system for the whole city, said New Orleans' homeland security chief, Terry Ebbert.

     

    "The challenge is an engineering nightmare," Paul Accardo, a police spokesman.

     

    "We are looking at 12 to 16 weeks before people can come in," Mayor Ray Nagin said on ABC's "Good Morning America, "and the other issue that's concerning me is have dead bodies in the water. At some point in time the dead bodies are going to start to create a serious disease issue."

     

     

    ....I think it's safe to say that the Bills game versus New Orleans will not be happening in the Superdome on 10/2.

  3. If you're talking about frame construction, when half the shingles are gone a roof pretty much IS destroyed.  I'd wager the standard is different for the Superdome...

     

    Plus...who among us knows how the roof on the Superdome is constructed, really?  I've heard three different descriptions of its construction now.  So who's to say the roof is or isn't structurally compromised?

    CTM...everything you ever wanted to know and more about the Superdome roof...

     

    SUPERDOME ROOF

     

    Contractors building the Superdome also found that it required efforts and techniques that were a bit out of the ordinary, especially in the construction of its roof. For this building, the largest clear span steel structure in the world (as attested to by the new Guinness Book of World Records) is literally held together by its roof. In its flying - saucer-shaped design , the walls of the Superdome literally hang (for want of more descriptive term) from the roof, with the force vectors at foundation level pointing away from the center.

     

    The uniqueness of the Superdome's roof, designed by Binkley Engineering Company of St. Louis (formerly Roof Structures, Incorporated) is its "lamella" configuration, which is nothing more than a series of overlapping triangles building out from a ring in the center. This gives stability against any downward forces. The Superdome's 75-ton, 124-foot-diameter (38 meters), gondola handing from the center of the roof, gives it a stability against upward forces as well.

     

    To build the 9.7 acre, 680-foot-diameter (205meters) clear span roof hanging (American Bridge Division of U.S. Steel Corporation was the contractor) required the use of 37 scaffolds in concentric circles, as well as mobile cranes.

     

    The entire Superdome was designed with the intention of making everything in it capable of contributing to the stability of the structure. Its superstructure has four main column lines as the perimeter of the building to support the building and the seat bents and meeting room spaces. The columns supporting the tension ring are on 22-foot (6.6 meters) centers, arranged in a perfect circle. The columns for support of the seat bents cantilevering 65 feet (21 meters) are set in two separate rows that make up the "Squircle" pattern (the interior of the building is slightly elliptical in shape). An outer row of columns frames the convention room area.

     

    Wind bracing is placed between the seat bent columns and Superdome columns, alternating between the three rows of columns and places where it doesn't interfere with the concourses or lobbies.

     

    The roof had to be analyzed separately because of its unique construction. First of all at the building's perimeter, K bracing extends out from the Dome columns to provide additional wind bracing and also to accommodate the rain gutters surrounding the Superdome' s 2,200 foot (660 meters) perimeter. The upper arms of the K's support the 96 sections of the gutter, each 22 feet (6.6 meters) long by 10 feet (3.1 meters) by 4 feet (1.25 meters) deep.

     

    Atop the 96 Superdome supporting columns rests the tension ring on 4-inch diameter (10 centimeters) rocker bearings. The bearings allow movement of the entire ring due to temperature contraction and expansion of about 3 inches (7.7 centimeters) in either direction from the column center ring.

     

    The 9-foot (2.8 meters) ring consists of top and bottom chords and diagonals of 14 inch wide (36 centimeters) flanges.

     

    Principal framing of the roof consists of 12 main rings at 30 degree intervals spanning from the 5-foot (1.5 meters) crown block to the tension ring. The ribs are connected by five concentric interior rings about 56 feet (17 meters) apart. Secondary trusses fill in and span from the intersection of main ribs and interior rings to the perimeter tension ring.

     

    American Bridge Division's efforts were crowned on June 12, 1973, a time that was referred to as the "most dramatic phase" in the Superdome's construction. It got underway at 6 o'clock in the morning, and was considered completed at 3:20 p.m. that afternoon, the Superdome's 680-foot roof (210 meters), the largest steel dome in the world was in place standing without support.

     

    But in the words of Thomas M. Sutter, resident manager for the Superdome's design team of architects and engineers, it wasn't quite that simple.

     

    As he put it later, "We didn't know for sure whether the roof would stand on its own until that moment." There were two men on top of each of the 37 towers used, and on top of these towers were hugh jacks. One by one, the jacks were lowered, inch by inch, until at last there were none supporting the roof.

     

    Much of the ribbed steel roof deck was raised from the ground by helicopter which often make modern builders wonder how they did it when the dome of St. Peter's in Rome was built. Of course, that took more than 150 years, whereas, the Superdome, begun on August 11, 1971, was opened on August 3, 1975.

     

    Topping the steel roof deck of the Superdome is an inch thick layer of polyurethane, and topping that is a thin layer of hypalon, which is a synthetic waterproof covering.

     

    The hypalon is a Dupont product and technically the name for it is chlorosulfonated polyethylene. A good description of the material would be that it's "elastomeric," which means that it has the capability of elongating under a load and recovering quickly from release of that load, much like a carpet.

     

    The hypalon covering, actually a liquid which has to be sprayed under pressure and then let dry because it is extremely sticky, was sprayed on the Superdome's roof under protection of special nylon bubbles (cocoons) which were erected to protect the spray from wind and the sun's ultra-violet rays as well. This entire roof covering procedure took 162 days. The cocoons were 110 feet (34 meters) wide by 200 feet (61 meters) long by 50 feet (16 meters) high. They were also used to apply the polyurethene.

     

    For those workers who must fix the stadium's field lighting and hoist TV gondola equipment, all of which are in the eight foot space between the roof and the top of the steel lamellas, there are four catwalks, each about three feet (.6 meters) wide, so that the workers can get close to the necessary fixtures.

  4. Plus...who among us knows how the roof on the Superdome is constructed, really?  I've heard three different descriptions of its construction now.  So who's to say the roof is or isn't structurally compromised?

    It looks like this site would probably contain the info you are looking for, but it is either no longer available or is temporarily down(maybe it is hosted in New Orleans).

  5. Now that gas prices are going to be close to 3.00/gal up here in the near future sooner or later .....steps will be taken in my house to conserve fuel consumption

     

    -No unnecessary trips...if it is not on the way home from work or to work then we don't go

     

    -dining out is going away

     

    -the wife is carpooling which will save us a ton of gas since we live 1 hr away from our jobs

     

    -cars tuned up

    Any other advice you can give or any ideas you may have would be great

    (wisecracks aside)

    I don't know if this applies to you but....Stop making pretend you are part of the NASCAR circuit when driving on the thruway(especially when you already have a gas guzzling SUV)! :D

  6. So what your saying is that our journeyman FB had his hands full with a perennial Pro Bowler and probable HoF LB? 

     

    Shocking.

    421273[/snapback]

     

    Just my 2 cents...

     

    First of all Urlacher is a long way from the HoF. Second, is it a lot to ask of your FB, to

    sitck his helmet in the chest of the player he is trying to block?

     

    I know it's preseason and all, but those were two LAME efforts by Shelton.

  7. My main source of concern is........surprise, surprise - the OL.

     

    420771[/snapback]

    Bill...I'm right there with you. The predictions of WM gaining 1500+ yards, is stuff dreams are made out of, if the OL does not improve in terms of run blocking. Here's hoping Gandy and Anderson are adequate, MW continues to improve, CV stays healthy and we can squeeze one more year out of TT at OC.

  8. I haven't had the chance to watch the game back on tape, but there were at least two plays where Shelton was completely ineffective as a lead blocker. One was on Urlacher and I'm not sure who the other one was against. If the running game is going to succeed, Shelton(when he is in the game) has to make his blocks.
