mosque in South Tower before and during 9-11
-
I am waiting to find out just how the buildings came down so easilly. At the time I was shocked at how they just collapsed. An airplane is an insignificant thing to a building. Many buildings have been hit by planes, none to my knowledge have collapsed (Soon after 9 11 a plane in Italy hit a uilding, then there was the Dutch plane that crashed into a tower bock in Amsterdam years ago). And given the buildings were supposedly designed to withstand a plane crash. Well, its just very surprising that they came down so fast. I shudder to think that the US gov/big business had a hand in it, but I wouldnt put it past the Americans. Nothing is more important than profit to them.

You're losing your touch. Surely you can come up with a more effective troll than this?

Having a degree in engineering and working in destructive testing for several years, the building collapse is as expected. Note that there are many reasons a building will or will not collapse, size of plane, where plane hits, type of construction, etc. Also note I have not done the calculations but have read reports on the collapse and talked to structural engineers.

Yep, read about this last week. You know, at first I wasn't sure if the Park51 center was a good idea, but I'm pretty firmly in support of it. Especially if, as they say, it'll have those "prayer spaces" for different religions, not just one for Muslims. Sends a good message of cooperation. I may not subscribe to any religions, but I support the right to practice them, since the same right guarantees my ability NOT to practice any... As the Pagans say, "An it harms none, do what ye will."

Many people forget about building 7. The building was not hit by a plane, it just had a small fire in it and then suddenly free-fell perfectly without warning.

And the building which apparently collapsed, and as the reporter was saying that it had collapsed it was actually visible and clearly standing in the background! And also the lack of any bits of the airplane that supposedly crashed into the pentagon, I googled it and found this pic: http://www.brasscheck.com/videos/911/pentagon-aerial.jpg[^] Certainly not a big enough hole for an airplane crash, looks more like a small explosion to me.

I saw the paper posted by Ravel, but I had heard something different. I had heard it was designed to withstand a 747 size impact (which that paper seems to suggest it wasn't). What I saw on the news afterwards was that it was designed properly, but not executed properly. The problem, as was reported, was with the insulation. Instead of using the insulation in the designs, it was constructed with spray-on insulation. The force of the impact caused a shockwave that literally blew all of the insulation off. This left the structural metal without any heat protection which lead to the weakening of the members and eventually the collapse of the building. But I'm sure there are other reports out there as to the cause of the collapse.
It was designed to withstand the impact of a 707 hitting it. Not a 767 and the fire resulting from it being fully laden with fuel. Contrary to what "super engineer" fat_boy might think, the tools to do that kind of analysis adequately when the Towers were designed did not exist. Considerable advancement has been made in finite element analysis in the intervening years, both from a structural standpoint but what is now becoming known as "multi-physics" where you can analyze many effects combined.

You mean like Youngs modulus of elasticity and polar moments of inertia of I beams? You really are a typical internet fuckwit sometimes: I used to be a structural engineer and designed steel work for buildings in the stone cladding business, Some of the project I wored on included stanstead airport and the broadgate and moorgate developments in london. As I said, I would really like to know how those buldings came down so easilly.

This was proposed soon after 9/11 and it makes sense. It would explain why the floors pancaked down on each other. What I dont get is how the building, being designed to withstand an inpact by a 707 failed in this way. It shouldt have. I also think that having floor not joined to the skin makes for an immensely weak structure. Itrs a crap design IMO.

The buildings were supposedly built to take an impact from a 707, a similar sized plane to those which hit the buildings. The design was poor. Not to tie the floors to the walls properly immensely weakens the structure. But how about WT7? How on earth did that collapse? It was almost untouched. A small fire, the impact of bulding debris. Many other buildings suffered similar fates that day without falling down.

The design didn't consider the fireproofing on the steel beams being blown off, which it was.

Unless you're secretly a structural engineer, your opinion in this matter isn't exactly worth much. You could put any really great design through very extreme conditions and watch it fail and then comment on how crappy the engineers are. Immensely weak structure? I think the towers did a fantastic job considering they had enormous jets flown into them at high speed and were practically hollowed out with fire.

I left structural engineering in 1989, IT pays a lot better, bur I still dont accept that a building designed in the days of paper and pencils to withstand an impact of a 707 should collapse so easilly. It was either a really bad design, or really bad implementation (and bad imnplementation is often the cause of bulding failure). I would also like to know how WTC 7 collapsed when other buldings in the vicinity, more heavilly afected, didnt.

Almost untouched? It had a tremendous gash in the side, about a quarter of the height of the building. But, like the twin towers, it wasn't the holes that toppled it - it was the fire. The gash lined up with the fuel system in the building, causing a horrific inferno. WTC7 collapsed for the same reason that the twin towers did, unlike the other buildings that failed to collapse.

Guess what... I used to design steel work for buildings.

Then you should be able to guess at how strong bare steel is when it's been exposed to 500-600 degree temperatures for an hour or so. How many of your buildings could survive an impact like those on 9-11?

And exactly how big a hole should a fragile aluminium aeroplane make in thick reinforced concrete? Were you expecting the delicate wings to cleave wing-shaped holes right through it? And there was an explosion. Haven't you even seen the security camera footage?

I didnt design any buildings, I used to design brackets and fixings used in stone cladding, so I cant comment. According to the link you sent a building is required to withstand a fire for 3 hours. The article also stated that the steel only lost half its strength at this temperature and thus was within its factor of safety. However the buildings collapsed in about an hour so there is obviously a faiulre somewhere, either in design or in implementation. Like I said,, not pinning the floors to the outer shell of the building is throwing away a massive increase in strength which wouldnt have been particularly more difficult to implement. Just a few bolts on each beam would be sufficient.
