WTC bldg. 7 - tallest building in 33 states?

Question

WTC 7 would have been the tallest structure in 33 states. NIST cant explain why it demolished itself.
Can you?
what happened to the fire insulation, the sprinklers? how did every floor fail, in order, all the way around?

FYI, im an architect.
but thanks for these 'all so obvious' explainations. you guys should write NIST and explain it to them cause they were baffled in the official report.

strutural steel bends, it doesnt break.
when heated, it acts like taffy. Not peanut brittle

hey mr. blank name
you have a phd in engineering? engineering what? lol, you dont have a degree.
Ever worked on a skyscraper? I have
And i do know about thermal expansion, and ductility. youre obviously trying to impress laymen here with vocabulary because the joints are the strongest part of the structure. Failure would have been slow, very slow. not all at once. The engineers and i in my office talk about this all the time. Are you even working??

Architects and engineers on the collapses

no name what planet are you on? ductile rerfers to TENSION. steel joints dont snap, especially when heated, the middle of the beams will snap first every single time.Wheres the deformations that thermal expansion would produce? wheres the ductile sagging of beams? just by your foul language and obvious ignorance, i know youre not a professional.

Answer 1

Because your mom leaned against it.

Answer 2

LOL. Really, you're an architect? Listen kid, getting a B.A. in architecture at some liberal arts college doesn't make you an expert on engineering skyscrapers. I'm sure you're a nifty little artist, but you don't know what the hell you're talking about.

You mention steel "bends." Wow. Did you forget about thermal expansion and the ductility of steel under strain? While you go look those words up in Wikipedia, let me say that no engineer that I know thinks that these 9/11 theories are anything but bullshit.

I've heard people say, engineers design these buildings to withstand the impact of a jet plane! Let me tell you, we DON'T. That is not a calculation that goes into the design of any building.

You conspiracy nuts take the cake. You guys take every grain of misinformation you can find and run with it.

@ LOL. You've worked on a skyscraper? I don't think so. Name your firm kid. You want to convince people. Name it. You are so full of ****. You say, steel will just bend like "taffy." LOL. Steel is ductile, but not like taffy. It will snap under strain. And, any sufficiently hot fire will create enough thermal expansion to snap joints. You want to talk engineering kid. Go ahead, prove that you're an architect who works on skyscrapers. Better yet, name a skyscraper that you've worked on. You can't do it because you're a liar.

Answer 3

Simple, after tons and tons of debris fell on it, and damaged the building some of the flameing debris caught WTC 7 on fire. Firefighters were pulled out of the building to avoid any further loss of life. So, WTC 7 is damaged and on fire. Inside some of the diesal fuel lines that fed back up generators ruptured and fueled the fire throughout the building.

After allowing the fires to ravage the building inside for over 8 hours that damage, along with the previous damage, plus the extra tonnage from WTC 1 and 2 sitting on top on WTC 7 collapsed the roof. Then the level below it, after having tons of concrete fall on top of it and the beems supporting that floor now had extra tonnage on top of it, plus the beems were weakend by 8 hours of fire led to the floor below collapsing, and so on and so forth. The extra weight smashing down onto the floor below made the building crumble.

Anything else I can help you with?

edit: awood and Ernest, did I get my answer backwards? I thought it fell from the top, not the bottom. Of course, I never took much stock in 9/11 Conspiracy Guesses, so I may have misunderstod the guy explaining the physics behind what happened. I thought it fell from top to bottom, am I wrong?

Answer 4

Ya know Gary , I was never sure about that until I took the time to watch a program devoted to showing all sides of the story . Yep it was on this week . And ya know what Gary , I'll tell ya , after watching and listening to all the evidence , one can only conclude that because the building was burning basically all day that it was quite clear that it fell because of melting and heat stress . Debris was shown falling from the WTC 1 or 2 and that ignited WTC 7 early on . They let it go because they had their hands full with everything else .
Just watch any show that speaks about it .
I do hope you can put this to rest Gary .

Answer 5

What a contrived question!

Gravity explains how every floor fell "in order", from bottom to top. The fire reached 800 degrees, hot enough to melt the steel structure supporting the core of the building, thus the implosion effect.

Answer 6

You conspiracy kooks just won't let this one go will you? Here is another conspiracy:
It was actually Liberals who hijacked those planes and Liberals who blew up the WTC, the Pentagon and crashed a plane in Pennsylvania. And it was Liberals who killed over 3000 of our fellow Americans. All just to make the Bush Administration look bad. Man, Libs are smarter than I give them credit for !!

Anyway, the insulation was removed because it had asbestos in it. You can thank Liberals and their nature-Nazi environmental terrorist pals for that one. It was not replaced with anything so the steel had no protection against the heat.

Answer 7

The fire was not hot enough to melt steel, but it was hot enough to weaken the steel and concrete that supported the building... the weakened structure could not support the weight of the building so it collapsed... nothing out of the ordinary about that, since it was a very tall building there was massive strain on the supports.

Answer 8

It was a conspiracy concocted by the house elves, munchkins and oompa loompas who were all sick and tired of emptying the garbage cans, cleaning up other people's sh!t in the bathrooms and vacuuming the floors all night in that building. It simply had to go, so they enlisted the help of the Bush Administration.

Since then, they whipped up a hurricane with fans and wooden spoons, and called it Katrina. They sat back, watched all the destruction with glee, and threatened "Dubya" to tell all about the Bldg. 7 conspiracy if he stepped in with aid.

As little sense as all this makes, I think it makes more sense than your question.

Answer 9

It's simple physics, really. The floor with the most weight on it is the first floor, so it's the first to go. Then the second floor has the most weight on it, and it has the impact of hitting the ground, so it goes. I hope have enough reasoning power to explain the rest of the progression to yourself.

Answer 10

If anyone can find structural steel that melts at 800 degrees, I will Kiss their ***!


Larry Silverstein said publicly that the building was "Pulled"! A term used by controlled demo companies when they demolish buildings! http://www.youtube.com/watch?v=7WYdAJQV100


Marvin Bush Removed Bomb Dogs 11 days Before 9-11 from WTC's!
