Like mentioned before we need some Structural Engineers here.....
Y'r Canadian friend,
Sven
So what would happen if a "structural engineer", let's say a very highly qualified one, told you "The only way those buildings could have collapsed the way they did was with planted explosives."?
Would you, first off, believe him?
Would you suddenly see the light and agree there is a possibility it was controlled?
Would you start to think for yourself?
Or would you dismiss the structural engineers claim, 'cause you can't wrap your mind around the reality of your government?
Or would you except what the engineer says because he's a self professed "expert", and start parroting the theories of the opposition?
Or would you think for yourself, and express your own views on the WTC problem?
I'm seriously interested in your answers Sven, I'd like to know, then maybe I can decide once and for all if you're really 8 yrs old, you're just a Troll, or you are a dis-info agent.
AP&F...
"Think for yourself, it could do wonders for the Human Race"

I'd would be the one to believe the engineer.

How does an airliner penetrating the building from one side, distribute the burning fuel to all 47 of these columns? I mean really this is an office building, that is built like a building within a building. You cannot get the fuel to spread evenly and heat all 47 of these columns to the same temperature, at the sames exact time to get this thing to collaspe all th way around at th same time.
If this was to happen, it would topple towards the entry point of the aircraft which at that point has become the structures weakest point.
Some will say, well the aircraft stripped the fireproofing from the steel. Look at those pictures there is no way that the fireproofing will get stripped off of the farside of the entry point of the aircraft. There is not any possible way you could heat it evenl;y at the same rate of time to get both of these buildings to go straight down.

I just wonder if anyone who received the WTC steel thought of testing it for explosives residue
before it was melted down?
The National Fire Protection Association (NFPA) released a study of high-rise building fires in September 2001. "This study indicates that in the 14-year period between 1985 and 1998 there were a total of 7 fire fatalities in all of the high-rise office buildings throughout the United States," says Schulte.
"NFPA fire statistics show that our nation has never been more fire safe (and firefighters have never been safer), yet the NIST report is written as if fire safety is a major problem in the United States," says Schulte. "As a fire protection engineer with 29 years of experience in the field, I strongly disagree with this conclusion. Since the early 1970's, there has been much progress in the fire safety field. I would hope that the Congressional Science Committee would begin asking NIST for its basis for proposing such radical changes in the fire safety field, particularly in light of the excellent fire safety record of commercial building and, in particular high rise buildings."

Okay. Let's start at the beginning.
- The impact of the aircraft physically severed a number of exterior columns where the plane hit the building and also a few columns opposite the impact point. For WTC 1, this was past the core area on the opposite side of the building. For WTC 2, this was on the opposite corner from the impact point.
- In both impacts, significant portions of the aircraft fuselage or wings swept through the core areas, destroying the exit stairwells, cutting water risers, severing elevator cables, and damaging the core beams and columns.

i notice the architectural record TOTALLY questioned MANY of the NIST recommendations.
notably, the historical(actual historical, LOL) record of fire preformance in office buildings has been EXEMPLARY.

Where in the world did you get that information? An aluminum aircraft goping through hardened steel support structures, all the way to the otherside? There is no way to even prove this because the buildings fell down and were obliderated.

You seem to think that the core walls were made of steel plate. They weren't, they were made of 2" thick drywall.

Now Howard, LGM referred to "hardened steel support structures". Why is it you rebutt with attempting to turn his comment of the core structure into a comment of drywall? He did not, clearly, say "walls" - he said "structure".
Surely, if a lowly construction worker understood his comment, you did - or was that a wasted attempted to divert?
Ugh

The impact of the aircraft physically severed ... a few columns opposite the impact point. For WTC 1, this was past the core area on the opposite side of the building.
We can't know the exact extent of the damage, but we can make reasonable guesses.
Common sense tells us that there were three major damage categories
C) The column received minimal physical damage, but the fireproofing was knocked of by the shock of the impact and force of the building and aircraft debris.
If you sever or significantly damage a column, then it can no longer carry the building loads it was designed to carry. Since these loads do not go away, the adjacent columns now have to carry the weight formerly carried by the damaged columns.
Other columns with less physical damage would of had the fireproofing scoured off by the impact forces.
Columns closest to the impact area would have been exposed to the heart of the fuel and building debris fed fires.
As these columns heated up, they would have gradually lost their ability to support the loads they were designed to support, and the additional loads transfered to them by the significantly damaged, nearby columns.
In addition to the damage to the columns, there was extensive damage to the floor slabs in the impact areas.
The impact damage, and the fires caused the floor slabs to sag, thus the forces that the floor slabs were exerting against the exterior and core columns changed from vertical compression forces to inward tension forces.
The change in the forces caused the exterior columns to bow inward significantly.
The bowing pulled the whole side of the building inward up to 10 inches.
This inward bowing further reduced the loads the columns were able to carry.
the gradual accumulation of changes to the loading of the columns caused them to fail one by one until a runaway collapse started. In other words, the remaining, undamaged columns were no longer able to support the building.
in both cases, the tops of the buildings rotated slightly toward the damaged areas at the start of the collapse. once the building started downward, however, gravity took over.
At some point the undamaged areas became unable to support the load that they were designed to support as well as the loads transfered to it from the damaged areas.
Steel is not that strong.
These buildings were huge. there is no way that they would have toppled like trees. the structure would not have withstood such a sideways movement.
There is a big hole in the middle of the south face of the building [WTC1].

Is that white hot enough for you?
Nuff said
Anyways, I'm off on vacation to Beijing. I'll be back in a week to read Howie's proofs. In the meantime, have fun debunking the lies everyone, and watch Howie's repeating things that have been debunked before. He's a sneaky little rabbit.
