WTC #7's collapse

I think it's obviously a conspiracy. Those people that think several millions of tons of steel and concrete hitting the ground right next door had anything to do with shaking building #7 off its foundation are truly nuts.

WTC #7's collapse

Does anyone know what the measured seismic stress was at the base of building 7 when the neighboring buildings collapsed?  

I would expect that the corner closest to the epicenter would flex more then the far corner facing away because of the way the force of the collapse is being transmitted through the ground, but unlike a normal earthquake, there would be a much quicker dropoff in force.

I wonder if it is possible that the small radius of the shaking could be the culprit?

The reason the twin towers collapsed was their exoskeletal framework failed. The towers had no interior support beam by design. All of the floors weight was held by the exterior walls similar to a spiderweb. It was a new and revolutionary design on a building that tall. The heat from the fuel fire weakened the exterior and it began to rip like a zipper. Once there was a failure the floors began to pancake. Engineers never factored in the asbestos removal either, which enhanced the heat's effect on the metal.

But what about bldg 7 RPM (AGAIN NOT THAT I THINK THIS NUT IS CORRECT OR ANYTHING FAR FROM IT) I'm just curious.

Did it fall from because of the stress it recieved when the other two fell?

I'm willing to bet if you were standing within a block of the towers when they fell you would have felt it. ;)

 The Palisades seismic record shows that -- as the collapses began -- a huge seismic "spikes" marked the moment the greatest energy went into the ground. The strongest jolts were both registered at the beginning of the collapses, well before the falling debris struck the earth.


The foundation supports the building and as the weight of a 30 story building is quickly removed from the foundation the foundation reacts with an equal an opposite reaction.    

So when the several thousand ton weight of the collapsing stories was removed from the typical building weight the foundation would have reacted upward as the compressive energy which supported 30 stories within the foundation was dissapated.

This motion of the ground would have been detected as the seismic motion that it was, before debris impacted the ground.  

>edit>The removal of weight was a more time concentrated change in energy than individual piecees of debris impacting the surface over several seconds and therefore would be a greater spike.

You guys try to do any searching on how many 'steel frame' hightowers or buildings in history have fallen due to fire?? I understand 2 of these buildings were struck by aircraft mind you, but fire is claimed to be the culprit for both WTCs and #7...  I did.. It is less than 4 by my searching.. Could be wrong.. Wish someone would show different..

Building #7 is not a foundation failure.. Unless the entire foundation dropped out at once.. Watch it fall....

(less than 4 but 3 happened in one day....)

Yes or no, Kappa... do you think the administration bombed #7, and by virtue of that guilt helped orchestrate the entire event? Clarify please, I'm trying to understand how insane you are.

I thought the burning aviation fuel melted the supports in the building itself. I would guess that most other fires involving this type of building did not involve anything other than burning upholstry, office equipment etc and not large quantities of combustible substances burning at high temperature.

I hear you Dowding.. But what gets me... No fuel in #7..... It was first distributed that #7 fell due to deisel fuel tanks igniteing, but they were found intact...

Interier fires will reach very high temps no matter what the fuel is..

if you guys don't start agreeing with him pretty soon ("open minded") he will start frothing at the mouth and calling you names.

Note how they never come up with conspiracy theories when "their" candidate is in power.

Lets stop beating around the "bush" so to speak, 911 was a CIA conspiracy. Here is the proof. Forget the airplanes, even the twin towerrs were brought down by controlled demolition!!!

Yeah, I've heard that the planes were actually full of fire retardant and the brave hijackers were trying to stop the upcoming demolition of the towers.
