Pete Posted August 29, 2005 Posted August 29, 2005 Probably. Last report I heard, Gulfport was getting hammerred. "Complete devastation" was the phrase that was used to describe it. And of course, they wouldn't exaggerate at all... Still, Gulfport was in a bad position after the storm shifted east. "Complete devastation" it probably isn't, but I wouldn't be surprised if the city was substantially wrecked. Apparently the coastal casinos suffererd badly early... 422100[/snapback] 10 feet of flood water downtown. Check out Jim Cantores situation. Gulfport got pummelled. Camille and Katrina- that poor town
Wacka Posted August 29, 2005 Posted August 29, 2005 If the eye would have been maybe 30-40 wiles west, all of NO would have flooded. They didn't know where it was headed until during the night. Downtown NO might still get flooded wwhen the surge comes down the Missisippi. It runs right thru the city.
LabattBlue Posted August 29, 2005 Posted August 29, 2005 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? 421970[/snapback] 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.

But it seriously makes one wonder how they're going to fix the damned thing. They certainly won't in time for the season, not if it takes half a year just to spray the hypalon.

Plus, we haven't heard anything about the condition of the field. With the rainwater coming through the holes in the roof, it could easily be wrecked.

If anyone did... You would hope they thought of drainage. I wouldn't bank on it, I've worked with too many "experts in their field". Watching CNN right now, the 'burbs east New Orleans sound like an absolute horror. The scary thing isn't all the people and animals calling for help (not that I'm callous to people in trouble, but a dog howling in panic unnerves me)...it's that it's getting quieter as time goes on.

BuffOrange Posted August 30, 2005 Posted August 30, 2005 I think we already answered that somewhere else. They could play at Ole Miss or any of the Louisiana stadiums that aren't significantly damaged. LSU will have to look for a new stadium too since they play at the Superdome as well, don't they? One thought might be the Astrodome, although I don't know how the Texans would feel about that. 421539[/snapback] LSU plays in Baton Rouge - Huge outdoor stadium with numbers every 5 yards. I would imagine the Saints would play there.
