Architects and Engineers for 9/11 Truth

[A W Smith]

Chris, show us how this

and this

can resist the collapse of multiple storys above it,

Gregory Urich disagrees with you

The floors supported the gravity loads and provided lateral stability to the external walls.

You are ignoring the fact that the core columns were mutually laterally supported by the floor girders between them on every floor. This creates a grid or matrix type structure that is capable of standing without additional lateral support.

The NIST FAQ, which is the official explication for the collapse says the floor supports broke loose from both ends.
They had no explanation for the collapse of the core at all.

I have also pointed out that all the falling floors did not impact the intact floor at the same time.

While we're at it, let's go back to that claim of yours about the large sections being ejected 600 ft... How powerful do you suppose such charges would need to be to get that result? More than this perhaps?

I don't know. The question is, what is the mechanism for converting enough vertical energy into the horizontal energy required to eject these 4 ton sections 600 feet.

Everyone keeps side stepping this critical question.
Do you know the answer?

Until it has been determined, no one can state that the collapse wasn't arrested as Prof. Jones states.

If the first floor doesn't arrest it the falling material will retain some of it's kinetic energy so when it reaches the next floor it will have more kinetic energy than it had when it hit the first, as well as having increased in mass. The collapse cannot take down a couple of floors and be stopped.

many columns of which remained standing for seconds after the floors around them collapsed. Your point?

The NIST FAQ, which is the official explication for the collapse says the floor supports broke loose from both ends.

Yes they did, they explained collapse initiation of the entire structure from the collapse initiation zone, once it began. "collapse was inevitable"

I have also pointed out that all the falling floors did not impact the intact floor at the same time.

they did not need to, again, explain how the floor framing diagrams i posted above can even resist dropping a single floor upon them.

I don't know. The question is, what is the mechanism for converting enough vertical energy into the horizontal energy required to eject these 4 ton sections 600 feet.

the mechanism as you call it. has been explained to you multiple times in this very thread. you ignore it, the exterior one quarter mile high perimeter peeled away as floor truss seats were severed and tumbled away. some of them landing 600 feet away. it is not unexpected. This is like asking how the top of a tree was "ejected laterally" when its top lands 100 feet away from a stump when it was 100 feet tall.

Everyone keeps side stepping this critical question.
Do you know the answer?

No one side stepped anything. It is a fact you have blinders on.

How in hell did you get that conclusion from my post?

This creates a grid or matrix type structure that is capable of standing without additional lateral support.

And... after the collapse initiated what happened to the floors which provided the lateral support? What happens to the core without them Chris?

The NIST FAQ, which is the official explication for the collapse says the floor supports broke loose from both ends.
They had no explanation for the collapse of the core at all.

Woah wait what? You say that the floor system helps to create a "matrix type" structure making the core capable of standing without additional support? I think you are confusing the building in its original state -- not the state it was in after the floor systems failed and were no longer acting their roles in supporting the structure...

I don't know. The question is, what is the mechanism for converting enough vertical energy into the horizontal energy required to eject these 4 ton sections 600 feet.

Well I'm just going by your claim that there is no other explanation for this other than explosive charges... They must be monsters to eject such large sections so far out... And they must be awfully special to avert the massive shockwave, or the ear shattering sounds with such power... I'm rather baffled as to why you don't see this problem with your own claims... My simple answer is the collapse provided all of the prerequisites.

Take 2 or 3 rectangular erasers and lay them end to end, pick up between your thumb and index finger and squeeze. I don't know if that occurred in this case but it's one way that forces applied in one direction can be translated into movement in another.

It would have taken hundreds, if not thousands of kilos of explosives to send a huge piece of steel flying hundreds of feet. It is not possible that that much explosives went off without being noticed.

Chris, show us how this

and this

can resist the collapse of multiple storys above it,

I don't dispute NIST's conclusion that:
[FONT=&quot]The vertical capacity of the connections supporting an intact floor below the level of collapse was adequate to carry the load of 11 additional floors if the load was applied gradually and 6 additional floors if the load was applied suddenly (as was the case).[/FONT][FONT=&quot]
[/FONT]They then incorrectly state that 12 [WTC1] and 29 [WTC2] floors were suddenly applied.

Most of the floors above the intact floor were still connected to the core and exterior columns and did not impact the intact floor at the same time.

No one has addressed this critical flaw in the NIST explanation.

Breaking the first floor never happened because the load was NOT suddenly applied!

Stop being dense.

The top section tilted, the columns broke and the top section fell on the floors below. The floors gave way, the perimeter columns fell away and the core collapsed sometime after.

Sorry, I meant the first floor after the collapse initiation.

Hows about you watch some videos in slow motion?

then come back and explain what you saw.

If it would take "hundreds, if not thousands of kilos of explosives to send a huge piece of steel flying hundreds of feet" then how did gravity do it?

Even if your statement makes any sense, which it doesn't, you do realize that both 12 and 29 are more than 11, correct?

You're a liar or blind then. If you're blind, tell me what you heard.

 

[Grizzly Bear]

Is it me or are C7's goalpost shifts getting all the more weirder?

Do you understand how a spring works?

 

[dtugg]

If it would take "hundreds, if not thousands of kilos of explosives to send a huge piece of steel flying hundreds of feet" then how did gravity do it?

For one, there was a lot of potential energy in the towers. You probably don't know what potential energy is. Look it up on wikipedia.

 

[alexi_drago]

Perhaps they used a trebuchet.

EDIT: that's just as an example of how powerful the effects of gravity can be, and compare that to the sound an explosive would make to have the same effect.
