@TLK

I am going to quote the reason of WTC7 collapse from the Popular Mechanics article

**According to NIST, there was one primary reason for the building’s failure: In an unusual design, the columns near the visible kinks were carrying exceptionally large loads, roughly 2000 sq. ft. of floor area for each floor. “What our preliminary analysis has shown is that if you take out just one column on one of the lower floors,” Sunder notes, “it could cause a vertical progression of collapse so that the entire section comes down.”

This reasoning is so mind blowing that it makes me mad. This is an insult to all the civil engineers around the world. What this literally is telling us that the whole structure was relying on one column. We design structures so the load is well spread out. That is why you have to drill holes in multiple columns and insert dynamite, when you need to bring a building down. Otherwise it would so convenient (and dangerous) to bring a whole building down, by just destroying one single column.

What our dear brother mercenery2k failed to see in the article is that Popular Mechanics’s engineers did not do the study, they are just reporting NIST that is a federal agency.

The whole structure is relying on multiple columns but coupled with gas explosions, even a single columns gives way, the entire strucutre becomes unstable.

Much like a bridge, if one pillar becomes damaged, that causes the entire bridge to loss coherence strucutre.

As for Popular Mechanics, if you can find any mathematial or engineering fallacy in what they are talking about, then please go ahead, prove it.

the fact that you can’t speaks volumes. and your rationale is ridiculous. they could not dig a foundation for WTC 7 because it was build over transmission lines and gas lines.

the new hudson yards complex being developed in West side of manhattan is being build over an existing rail line and will rely on a similar engineering principles of pillars holding up the building.

Jeeez…
