skyscraper fire in Dubai

[Sinobas]

Here's another skyscraper that had a fire on the majority of floors, and burned for 12+ hours. Contrast that to the world trade center towers, which burned for under 1 hour with fire on only a few floors.

Notice how it didn't collapse. The WTC are the only steel framed sky scrapers in the history of the world that have collapsed due to fire.

You do realize planes crashed into 2 of the buildings and the debris of those two buildings crashed into the 3rd building right?

Ya, fire alone did not take down the WTC. A combination of effects, some weakening others.

Oh no, I didn't know that.

Do you realize that planes didn't cause the collapse? Even according to the official NIST investigation, fires were the reason they towers collapsed. It was about fire weaking the steel.

• The two aircraft hit the towers at high speed and did considerable damage to principal structural components (core columns, floors, and perimeter columns) that were directly impacted by the aircraft or associated debris. However, the towers withstood the impacts and would have remained standing were it not for the dislodged insulation (fireproofing) and the subsequent multi-floor fires. The robustness of the perimeter frame-tube system and the large size of the buildings helped the towers withstand the impact. The structural system redistributed loads from places of aircraft impact, avoiding larger scale damage upon impact. The hat truss, a feature atop each tower which was intended to support a television antenna, prevented earlier collapse of the building core. In each tower, a different combination of impact damage and heat-weakened structural components contributed to the abrupt structural collapse.
• In WTC 1, the fires weakened the core columns and caused the floors on the south side of the building to sag. The floors pulled the heated south perimeter columns inward, reducing their capacity to support the building above. Their neighboring columns quickly became overloaded as columns on the south wall buckled. The top section of the building tilted to the south and began its descent. The time from aircraft impact to collapse initiation was largely determined by how long it took for the fires to weaken the building core and to reach the south side of the building and weaken the perimeter columns and floors.

I was going to launch into a dissertation on metallurgy and elevator up draft effects on jet fuel... Then I thought fuck it.

1 - when were the buildings built and to what codes
2 - jet fuel
3 - concentrated burns vs. more general burning.
4 - planes
5 - steel types
6 - core structure vs. cage structure

just a few big differences off the top of my head. I'm not looking into this any further, it's a fools errand since the situations are so drastically different it's like comparing a tuna and a lilly since they both live in the water.

I'm so tired of this shit. We print money like there's a shortage of Monopoly games at WalMart.

Let's build a new tower with everyone watching and a company hired to oversee the build (just not the one that certifies the NBA draft lottery)

Make sure it's built exactly the same and crash an empty plane full of fuel in it and be done. I suppose we'd have to wait until the building aged to be sure. I guess we could build 2, try the first one and if that doesn't work wait decades and try again.
