FEMA Deceives Nation About Twin Towers Core

[manu1959]

So what is your point? Can you read? We know you have no evidence. We know you cannot write and make sense.

found pictures of the rebar cages for the concrete core.....

notice no rebar in that photo either
we see steel columns, no concrete or rebar

hmmmmmmmmmmm....no rebar.....yet the core is claimed to be concrete......

 

[Christophera]

hey dumbfuck, which one DIDNT i remove

So what is your point? Can you read? We know you have no evidence. We know you cannot write and make sense.

^^^^^^^^^^^^^^
a classic case of projection

A classic case of non sense with no evidence from agents supporting the secret methods of mass murder.

FEMA misrepresented the structural core of the Twin Towers. They said it looked like this.

Then on 9-11 for the core of WTC 2 we see this, which can only be a concrete tubular core.

 

[Christophera]

ok. lets try it again.

concrete

An example of misinformation leading to efforts of disinformation. That is the freedom tower. Built just like the Twins, with a concrete tubular core, but they have a new hydraulic, climbing form.

steel

The concrete walls were cast inside the exterior steel framework using it to support outer form work.
This is the east wall of the WTC 1 concrete core shear wall falling into the empty core area. This would be the narrow end of the rectangular concrete core where the interior box columns had their long axis running perpendicular to the long axis of the core.

Sept. 13 - Leslie Robertson, one of two engineers who designed the World Trade Center,

“Beyond the reaction that any citizen has—the sadness that we all feel—you have to understand, I worked long hours, seven days a week on this project back when I was young and energetic,” says the 73-year-old, his voice breaking with emotion. “It was just terrible to watch, painful and horrible.”
Still, Robertson, whose firm is responsible for three of the six tallest buildings in the world, feels a sense of pride that the massive towers, supported by a steel-tube exoskeleton and a reinforced concrete core, held up as well as they did—managing to stand for over an hour despite direct hits from two massive commercial jetliners.
“If they had fallen down immediately, the death counts would have been unimaginable,” he says. “The World Trade Center has performed admirably, and everyone involved in the project should be proud.”

did you type that all by yourself......got any pictures of the rebar cages that reinforced your concrete core.....

LIAR
the freedom tower is NOT built like the twin towers were

it was published that way, and if you notice, words actually spoken by Mr Robertson are in QUOTES
notice what ISNT

and when this was pointed out to him, he said he never said that nor did he read the story till it was pointed out, and thus it was too late to ask for a correction
since it was YEARS later

Fo about 40 pages now you have completely evaded stating if you think Robertson did not demand a correction after 3,000 were killed in what was termed a collapse of a building he was an engineer of, or if Newsweek refused to correct.

Your post is non sense, and you refuse to even try to make sense of it.

where are the rebar cages for your concrete core.....why do all the construction photos show a steel core....

 

[Christophera]

Part of the top of the WTC 2 concrete core falling onto WTC 34.

Then, after all of the steel exoskeleton fell, the top of the core detonated with explosives, leaving just under 1/2 the height of the concrete tubuler core.

After more explosives detonated, the core was further down yet.

No steel core columns are seen n the core area.

On 9-11 after all the steel exoskelton was gone, and the core walls had been detonated with high explosives, the rebar stood under where the spire had been.

 

[manu1959]

found any pictures of the rebar cages....how about the special inspection certs for the rebar....shop drawings....shippping manifestos.....purchase orders....anything.....

you don't know what a rebar cage is do you.....

 

[Christophera]

FEMA states the core looks like this,

But on 9-11 we see a concrete shear wall behind the interior box columns of the north wall of WTC 1 and the core behind is empty.

After high explosives were detonated again, the spire fell

This was just before the spire falling, the east core wall of WTC 1.

wrong again fucktard
i have said NUMEROUS TIMES he never did
and WHY

here is christophera

wash, rinse, repeat

again you repeat this same debunked bullshit

 

[Christophera]

There is no evidence showing the supposed steel core columns in the core areas of the Twins on 9-11.

Construction images are misrepresented by stating that the elevator guide rail support steel is "core columns"

In the photo below there are "butt plates" seen on the tops of the guide rail support steel left and right of the central crance.

Those butt plates are of inadequate strenght for joining core column sections. They re convienent for guide rail support steel because the holes in the plates can be elongated to shift the upper plate and shims can be used to thilt the upper sections.

 

[Christophera]

NIST hired Bazant to create a mathematical model of collapse when they failed.

This is the 3rd revision, the first 2 were ripped apart by other engineerr. Northwestern U took the pdf down after a bout six month to avoid that again, plus the mention of the concrete core was undesireable for upholding the secrete methods of murder.

It includes an estimate of the amount of explosive needed and the assumption they could not be placed while also adding a mention of the concrete core walls.


Collapse of World Trade Center Towers:

What Did and Did Not Cause It?

4, Abstract: Previous analysis of progressive collapse showed that gravity alone suffices to explain the overall collapse of the World Trade Center towers. However, it has not been checked whether the allegations of controlled demolition by planted explosives have any scientific merit. The present analysis proves that they do not. The video record available for the first few seconds of collapse agrees with the motion history calculated from the differential equation of progressive collapse but disproves the free fall hypothesis (on which the aforementioned allegations rest). Although, due to absence of experimental crushing data for the lightweight concrete used, the theory of comminution cannot predict the size range of pulverized concrete particles, it is shown that the observed size range (0.01 mm – 0.1 mm) is fully consistent with this theory and is achievable by collapse driven gravity alone, and that only about 7% of the total gravitational energy converted to kinetic energy of impacts would have sufficed to pulverize all the concrete slabs and core walls (while at least 158 tons of TNT per tower, installed into many small holes drilled into each concrete floor slab and core wall, would have been needed to produce the same degree of pulverization). The exit speed of air ejected from the building by the crushing front of gravitational collapse must have attained, near the ground, 465 mph (208 m/s) on the average, and fluctuations must have reached the speed of sound. This explains loud booms and wide spreading of pulverized concrete and glass fragments, and shows that the lower margin of dust cloud could not have coincided with the crushing front. The resisting upward forces due to pulverization and air ejection, neglected in previous studies, are found to be negligible during the first few seconds of collapse but not insignificant near the end of crush-down (these forces extended the crush-down duration by about 4%; they augmented, by about 25%, the resisting force due to column buckling at the end of crush-down, and doubled that force at the beginning of crush-up). The calculated crush down duration is found to match a logical interpretation of seismic record, while the free fall duration is found to be in conflict.
