Because US govt did set if to collapse

Duh















Serious answer....probably lots of fire resistant asbestos on structural members

Because a plane didn't smash in to it?

The fire was more intense outside than inside (due to the flammable cladding).

Perhaps having a 767 knocking out a couple of floors of support beams before the fire started had something to do with it.

I don't know about the 3rd WTC bldg though.

Because a building or two didn't fall on top of it.

UK building codes call for a building to be able to withstand an explosion that damages/destroys a structural beam/column of a building.....in other words, remain standing if one of the structural supports is destroyed. This code is due a gas line explosion that happened in a UK tower in 1968. The US doesn't have such a requirement.

quote:

As explained by Dr John Knapton, emeritus professor of structural engineering at Newcastle University, it all has to do with a change in regulation in 1971 after a gas explosion at a high-rise in East London. "I don’t think this building will collapse because in 1968, a block of flats at Ronan Point in East London partly collapsed as a result of a gas explosion in a kitchen," he told The Telegraph. "As a result of that, the design of tower blocks in the UK changed from about 1971 onwards. From then on, the design had to allow for an explosion or a fire to remove part of the supporting structure and for the building to remain standing. "

It would have collapsed if it was built 4 years earlier

Grenfell Tower was completed in 1974, so would have needed to comply with strict new regulations which ensured buildings would not fall down in the event of a blast, or a major fire.

Building 7 was split open by the North Tower falling down on it. That video is shot from where the North Tower was behind Building 7. Building 7 had a huge gash on the other side that you can't see. It was structurally compromised when the North Tower gashed it open.

Made it didnt have a hollow weak core structure like the towers did according to the 9/11 commission.

quote:

For the dimensions, see FEMA report, "World Trade Center Building Performance Study," undated. In addition, the outside of each tower was covered by a frame of 14-inch-wide steel columns; the centers of the steel columns were 40 inches apart. These exterior walls bore most of the weight of the building. The interior core of the buildings was a hollow steel shaft, in which elevators and stairwells were grouped. Ibid. For stairwells and elevators, see Port Authority response to Commission interrogatory, May 2004


But as you can see the core had more to it than the outside columns

No it didnt at least not according to the NIST report.

quote:

Other than initiating the fires in WTC 7,** the damage from the debris from WTC 1 had little effect on initiating the collapse of WTC 7**. [...] Even without the structural damage, WTC 7 would have collapsed from fires having the same characteristics as those experienced on September 11, 2001." :: NCSTAR 1A, p. xxxvii

Because it's made of f&%king concrete and it didn't have a fully loaded down airliner crash into it?

Because the fireproofing material did it's job.

WTC collapses were due to removal of insulation and intense combustion caused by hundreds of gallons of jet fuel that weakened the support structures of the building.
