They did analyse the the potential effects of the ensuing jet fuel fire. The analysis concluded that the structure would survive. Unfortunately reality failed to conform to the design models.
For starters, would you happen to know of any structural materials that can tolerate corrosion for that period?
Masonry - Many such bridges are hundreds of years old. Some are even thousands of years old!
Reinforced Concrete - Again, 100+ year old RC bridges are common.
Prestressed concrete - Not quite as old as some RC bridges, but again, 100+ year old examples are common.
Steel - Our Sydney Harbour bridge is 70+ years old. No it's not magical gold plated or ceramic, it's plain old steel with a sufficently robust anti-corrosive covering. It will be around for at least another hundred years.
I design structures, and I generally design them for 50 year design life. I don't like it, but it's the economic reality. Make no mistake about it, it's an economic contraint, not a physical contraint. If you don't provide a design solution that shifts costs onto future generations then the customer will find an alternate vendor who does.
For real. It is a scientific fact that rape babies are devil spawn. As such they must be terminated with extreme prejudice. Anyone who doesn't believe this needs to watch the Nightmare on Elm Street series. This documents fully the dangers that can arise when rape babies are allowed to come to term.
Tell me about it! I've been rewiring my stereo speakers and I pretty much have to kink the wire around one corner to make it fit. I'm getting the worst bit-turbulence at the kink. It's disrupting the music to the point that not even my shaktis can clean it up!
Exactly. People have this perverse idea that "survival of the fittest" means that killing is natural, and that the deadliest, meanest creature who slaughters all the others is somehow "the best".
A very long time I would think. Consider race for example. It's far blurrier than gender, some argue in fact that it's arbitrary, yet we still have race firmly embedded in our laws and customs.
Little Girl: [looking at a Magic Eye poster] Wow. It's a schooner. Willam Black: Ha ha ha ha. You dumb bastard. It's not a schooner... it's a Sailboat.

Hopefully, by that point, you'll have learned how not to Godwin yourself.
Damned Godwin-nazis...
I like the switch on Aussie sockets, but you have to be real careful to switch off unused sockets or a lot of electricity leaks out costing you $$$.
UK/Europe use whole-life concepts to determine bridge design life. So yes, their design life is longer than what US bridges are designed for.
I believe US bridge are currently designed for 75 years, which is still way too short.

The morality of the parents is irrelevant. Whether the father was a rapist or the mother a whore makes no difference to whether abortion is ok.
Admittedly both sides are guilty of resorting to crude moral rhetoric in justifying their positions.
You forgot rape

Just for this, I'm gonna download TWICE as many mp3 tonight to show those corporate FAT CATS they can't push around the little guy!
I can already find a ton of Marge Simpson pr0n on the internet.
Yeah but they are photoshop fakes, whereas these playboy pics are real.

Where did the poster say they wanted to promote ignorance?
When he suggested that data should be faked so as to conform to incorrect notions of reality.
With this new Imperial Probe Droid those rebels don't stand a chance!!!!

a few of the other Aussie commenters on here have also said they thought "teens" referred to 10-19, so perhaps it's an Aussie thing.
No it's not an Aussie thing. Everyone in Australia knows "teen" means 13-19.
Space sets had those nifty bazookas too
No, they were a "camera with side sight" (http://www.peeron.com/inv/parts/4380). See, those spacemen were just shooting film, not baddies.
And this one (http://www.peeron.com/inv/parts/4349) is a "loudhailer" - you know, for making announcements on the lunar surface...
having to 'stick it out' is only a by-product of religion
So what about our other moral ideas? Do you believe they are mere by-products of religion?
I wouldn't say it's totally different, because in both cases you have a person deciding life is no longer worth living and then killing themselves.
In fact certain pro-euthanasia groups argue that euthanasia should be allowed for people with depression.
Oh get over it. Just be a man and face up to the fact we've been doing it wrong the past few decades.
I know where you're coming from, but "570-fold" does mean 570 times greater. It doesn't mean 570 doublings.
The analogy is zig-zag folds, not doubling folds.
Depressed people WANT to be depressed
Fuck you.
You may as well walk into a cancer ward and say "You people WANT to be this way"
The only outcry I heard was Israel screaming "ANTI-SEMITISM!!" when the reports surfaced.

Speaking of cars, ask her what is the most important thing when buying a new car - its color, or how cute it is.
Either answer passes the test.
Anyone have an idea of the recommended system requirements?
