Possible design flaw found in collapsed U.S. bridge
Reuters ^ | 8/8/07 | By Benno Groeneveld

Posted on 08/08/2007 3:28:55 PM PDT by Jewels1091

A week after a deadly bridge collapse, U.S. Navy divers cut through tangled debris with underwater torches and saws on Wednesday in the search for victims while investigators identified a possible flaw in the 40-year-old span's design.

Bush was around 40 years ago. Could be.

your taxes will go up because some design engineer decided he was smarter than you.

A post gleened from the DU website:

Yep, while Bush was AWOL for 4 months because of his drug addiction, his pappy requested that the Army Corps of Engineers have him design this bridge so that he would not have to go to Vietnam.

Still, the bridge was under design when Kennedy was President. If "W" can be blamed, so can JFK, and since it was a design flaw, JFK has to be blamed.

The now discredited former President must be disinterred and removed from Arlington National.

Only heroes may be buried there ~ arch "bridge design" criminals must be prohibited.

That’s what it looked like to me. Seemed a little lightly constructed to me.

Meanwhile,...the Brooklyn Bridge is still standing and looking great.

A walk over the Brooklyn Bridge is one of New York’s pleasures.

National Transportation Safety Board investigators said they had found a potential design problem with gusset plates, or steel plates that tie together angled steel beams of the bridge's frame.

Investigators are trying to verify loads and stresses on these plates at specific locations as well as the materials used to construct them.

Officials stressed the finding is preliminary and would not say exactly where the plates were located or whether failure would have caused the collapse.

"We are continuing to make progress on this investigation, and each area of inquiry gets us closer to ultimately determining the cause of this tragedy," National Transportation Safety Board Chairman Mark Rosenker said in a statement.

This is really irresponsible reporting. Some reporter asks an investigator what he was doing, to which he/she gets an answer like "well, right now I'm inspecting the gusset plates". Which-- the reporter then spins into a finding that something has been found regarding these plates. Except, they go ahead and report that no, that's not actually the case and there's still a lot of things to look at before any findings can be made.

But that doesn't stop them from inventing a headline that is simply not supported by the article.

This bridge was found to have significant structural deficiencies as long ago as 1990. No doubt a lot of them were just needle-gunned and painted over and ignored. This tragic failure was a result of neglect, plain and simple.

It's not any different from asking the poor official, "Any signs that this is related to terrorism?" and the official responds, "No, we have no indication at this time that this incident is related to terrorism."

Headline: "NO LINK TO TERRORISM, OFFICIAL SAYS."

And nearly everyone (including here on FR) falls for it.

Designer from 40 yrs ago is probably dead. Blame him. Firm that built bridge has new personal and that did not build bridge. Blame them. State and Local officals who saw bridge every day and saw reports on its condition, did not do enough. Don’t blame them. Take monies alloted to transportation and build a new camp ground and name it after A representative from Congress a Former Mayor or City Councilman, go blameless. Same happened in New Orleans and happens all over US regardless of party affiliation.

“possible flaw”

The flaw is that it falls into the river. I knew that without even looking at the evidence.

What I find interesting is buildings are designed with a limited lifespan (meaning not forever). The iron develops fatigue issues (among other problems). Buildings like the Empire State building will either have to be eventually torn down or stripped and worked over internally for it to remain up. These building were placed in densely packed areas and were not designed to be taken apart.

What will they do - if anything?

so the question becomes (as it always was): We have given government more than enough money to provide for proper upkeep of this bridge and other infrastructure. Why should we trust government with more money when they have not proven they can be responsible with the amount they already have?

It’s had a giant monkey climb to the top, and it’s been hit by an airplane, and there was hardly any damage. I think it will be around for centuries.

There was a SC-bomber thread from a couple days back where knees were jerking like crazy. Not with regard to the possible terrorist connection, mind you, but with regard to the FBI.

It's possible to demolish a skyscraper (even without imploding it) in an urbanized area with only little disruption to the surrounding area.

It can be done. Not cheaply (depending on the construction), maybe . . . but it can be done.

Sorry ~ missed it. Only SC bomber thread I got onto was the first one and that's when the cops were not revealing any information.

Everyone on the thread at that time seemed to believe we'd find out these guys had one or more bombs AND had Arab names.

Turns out they had more than one bomb AND had Arab names.

The way the cops withheld information told everyone what the case was.

The FBI came in later, right?

Bush’s fault; tax cuts fault; not enough money for roads, bridges rebuilding; it is a plot to RAISE TAXES to blame tax cuts. They are now pushing for a rise in gas taxes nation wide. Rush spoke long about this today and some fund that was suppose to be set up with certain taxes to do all this, but the libs spent it on social programs, just like they did SS.

My tinfoil hat wearing little brother, who lives in Minnesota called me today to tell me he thinks the republican governor Pawlenty took the bridge down on purpose so that the feds would come in and build a new one at no cost to Minnesotans. I almost hung up on him and told him to quit smoking so much pot as it clearly has fried his brains.

I'm making a bigger deal out of it than it really is . . . I remember one thread where the headline read something on the order of "FBI says no known link to terrorism." [emphasis added]

A good number of comments on the thread read as if the word "known" did not exist in the headline. But the inclusion or exclusion of the word makes a huge difference, especially since it was the day after the arrests.

Psst. I'll give you one of my patents, gratis.

It's a carbon fiber structural paint.

By the time those buildings wear out the internal steel, you'll be able to just paint it on and forms a hard candy shell!

That's a good question, and something I've wondered about before too. Controlled demolition can work some miracles, but still, there's limits on how small a footprint they can drop something like oh, the Sears Tower in Chicago into.

If you can't go ahead and clear everything within a half a block or so... it's all going to have to go down through the elevators one bite at a time. It would be slow and expensive.

Yeah, but Christine would have made it much more dramatic ~ she'd gone out there and pulled those kids out of the bus and tossed them in the river to up the death rate.

At the moment almost every politician in America is slightly more honest and forthright than Christine.

The essense of engineering is to build the structure with just enough more strength in it than the greatest stress that shall ever applied to it. Unfortunately, none of us are sufficiently prescient enough to realize that the greatest stresses are often in some manner or effect beyond what can be imagined.

The Brooklyn Bridge was vastly overengineered and overbuilt, when the sheer brute strength of massive steel was counted to stand up well enough to any stress known at the time. And given that the materials available at the time were in many ways inferior to the best available today, that strategy worked well.

But engineers work under the gun from the bean counters too, as seen in high-dollar manufacture and construction of some of the modern machinery of life. “Make it a little cheaper” is the mantra in any number of engineering firms, while trying to emphasize that the cheaper design equals or exceeds to original specifications. But not by too much.

Suppose, say, that someone endeavored to construct a bridge using carbon fibers. Light, strong, and relatively resistant to the woes of vibration, weathering and oxidation. But an absolute bear to fabricate, and with the intricacies of design that are part of a bridge design, probably so prohibitively expensive to scale up that it would not get beyond model construction stage.

The fact is, that the design flaws in a highly engineered structure may not show for YEARS, or even never, if the excessive stress just never takes place. The design flaw of the World Trade Center, for example, was that when its internal steel supporting structure is heated above a certain temperature, it would collapse down upon itself. And this was because of a circumstance that nobody had imagined, that the burst tanks of a nearly fully fueled up jetliner would support a hot enough flame to cause the vertical members of the framework to be heated to the point where the steel became plastic and unable to support the weight of the floors above. The original design of the WTC allowed for the fact that a simple impact of the structure by an airliner traveling at 400 MPH could be absorbed by the building’s design, without compromising the integrity of the structure. But it did not allow for a subsequent fire in which temperatures would reach 2,700 degrees, causing the collapse.

The explosion that occurred in the basement of the WTC in 1993, while it caused a considerable amount of damage in the immediate vicinity, proved the original design concept was correct. The stress applied did not exceed the design limits. Conclusion, the engineers had built well. And the structure was still a splendid example of design superiority as of September 10, 2001.

just TRY to put an addition onto your house without a local inspector demanding a copy of your prints and crawling ALL over them... and i guarantee you, no matter how GOOD they are, he'll find something to piss about.

so who's signed off on the design inspection on this bridge???

We must note here that the same gang of Democrats hired by John F. Kennedy designed this bridge and the Viet Nam War.

You recall the safe refuge the NVA had over the border in Cambodia and North Viet Nam, and the several years where American troops were not allowed to fire back at the VC and NVA.

They also set up the one year individual rotation cycle ~ and several other abuses that seemed to be designed to make sure we would not secure the peace in RVN.

Obviously they didn't design bridges any better than they did wars.

We all know the gusset plates were hit by a SAM fired by terrorists. But the sheeple will buy anything the NTSB says.

I’d take it with a grain of salt. In usual MSM fashion, the article also states the bridge had 8 lanes. I believe it was 4.

They'll take it apart one piece by piece, floor by floor, opposite of how it was constructed. This is how the 40 story Deutsche Bank damaged on 9/11 is being deconstructed.
