yeah that's what i meant. just because the towers were unique doesn't mean they were weak[er]: that's a preposterous thing to say.
It's not that the buildings were any stronger or weaker structurally. Since we're talking about fire and steel buildings, why do you think that fire proofing was included on the trusses? It's because the danger from fire to a steel frame building does, in fact, present a danger to them...
For all you CTs, here is a case confirming the view that the steel frames are vulnerable to fire: http://www.concretecentre.com/main.asp?page=1095 The Madrid Windsor Tower Building Fire, 14-15 February 2005 The building totalled 32 storeys, with 29 floors above ground and three below. Concrete structure ran up to the 16th floor. Above it there was a core concrete column and perimeter steel columns. The fire started on the 21st floor. The steel columns above the 17th floor suffered complete collapse. The similarity to the WTC is striking. "The only part of the building to collapse was the network of steel perimeter columns supporting the slab on the upper floors.... NIST's interim report on the World Trade Center disaster recommends the inclusion of 'strong points' within the building frame design - the Madrid Windsor Building's strong points were its two concrete 'technical' floors and the concrete core system enabling the building to survive complete burnout. This case study is an example of the excellent performance of a concrete frame designed using traditional methods and subjected to an intense fire. It also highlights the risks when active fire protection measures fail or are not included in steel frame construction." Did they also use thermite in Madrid?
that's the bullshit u've been told by fema. both towers cores were surrounded by 17inch thick concrete and outer walls. below is a decription of the towers construction that proves fema was incorrect assuming the cores were naked. and mind u...this is not a conspiracy driven research.
well, fema didnt even say they were naked. just that the concrete core was much smaller then it really is. this has other implications since one of the planes hit the tower diagonally and didnt touch the core at all. how did the fire attack the core columns if they were protected by concrete walls?
puzzle: what's that black object flying past the towers? could it be a missile...maybe missing its target? gawd only knows. http://www.sunjambooks.com/wtc2ndeast.mpeg
