In England, a high-rise building must have concrete-encased stairwells that resist fire for, I think, two hours and which provide safe, rigid escape routes. Structurally, they often form the trunk of the building, from which lighter steel/concrete structures hang out like branches; that`s how you can have walls of glass, for instance.

In the Twin Towers, the stairwells weren`t concrete-encased, they were just braced with steel beams with some kind of fire-resistant covering, which didn`t prevent the steel getting hot. Unfortunately, when steel gets hot it loses strength even faster than burning timber. Look for the 20-minutes-into-the-fire line on the bottom axis of this graph:-



After 20 mins, a piece of timber still has 50% of its strength; a piece of steel has about 7% - it`s about as strong as Jell-O. That`s why the buildings appeared to implode; they just collapsed under their own weight.

Of course, after the event, no-one was very keen to put up their hand and say, "I allowed that building to be constructed on the cheap", so in the US there might`ve been something of a hushing-up conspiracy. In Britain, though, all of the above was reported in a very reputable construction-trade journal about one year after the tragic events of 9/11. ( May all those poor people R.I.P.)




^ I so hope neither of these are true.

And that is a known fact to most on here.

If you actually made some attempt to explain your point of view or even tried to circumvent that point of view, people may actually give you the time of day. Instead of the usual fuck off troll response (excuse my French here) that you're getting at the moment.
