If It's Bad.....Jews Did It

[eots]

Key findings include:

• Floor sagging and exposure to high temperatures caused the perimeter columns to bow inward and buckle—a process that spread across the faces of the buildings.
• Even though the jet fuel on the planes burned off in the first few minutes after impact, there was enough office furniture to sustain intense fires for at least an hour.
• The original builders of the twin towers and those who later renovated the structures did not have a clear technical standard for deciding on how much insulation to use around the structural beams, many of which gave way in the intense heat.

the case of the Twin Towers NIST only gives a theory of collapse initiation and never even attempts to explain the proceeding rapid collapse

 

[eots]

What you wont see is the steel structure was manufactured to take a static load bearing in a downwards direction of the calculated maximum weight plus a safety factor of 10%. This was calculated across the whole area even though the main support structure was in the central column of lift shafts. If any one of those central columns was to give the whole weighjt of the building would exceed the safety margin for the rest of the buildings central structure. This combined with the heat from the aviation fuel fires would compound the problem and the steel would explode as it reached critical temperature.

I have seen nothing of exploded steel but plenty about the collapse of heat-weakened supports.

That is what happens when the steel is weakened with heat, the maths and science is very complex but imagine a forest fire and all the animals running away from the fire. Well that is what happens to the inclusions in the steel when they run away from the source of the heat. This leaves a very brittle poor quality cast iron that cant take the weight, so it explodes as a closed can of soup does when heated. It is not an explosion as in dynamite or plastic, but the sound and effects are the same. I saw a stainless steel plate explode into millions of needles when the water cooling was not set right, we were collecting them for 6 months after

NISTs forensic testing of wtc steel showed no signs of the temperatures sufficient to weaken steel

That's a typical 9/11 CT lie necessitated by the fact that the truth just doesn't support their CT silliness.

It as quote is from the former NIST CHIEF FIRE INVESTIGATOR..you are calling him a typical liar /CT ?...on what basis

Reputable engineers and scientists and witnesses disagree. The heat with the jet fuel was enough to weaken the structural supports, and with all the weight they were supporting, the buildings collapsed. IF it was an "implosion" it would not have been SO gradual. Common sense wins again.

Buckling Steel
Dr. Shyam Sunder, lead investigator for NIST's building and fire safety investigation into the WTC disaster, said, "While the buildings were able to withstand the initial impact of the aircraft, the resulting fires that spread through the towers weakened support columns and floors that had fireproofing dislodged by the impacts. This eventually led to collapse as the perimeter columns were pulled inward by the sagging floors and buckled." "The reason the towers collapsed is because the fireproofing was dislodged," according to Sunder. If the fireproofing had remained in place, Sunder said, the fires would have burned out and moved on without weakening key elements to the point of structural collapse." - Latest Findings From NIST World Trade Center Investigation Released

"According to Shyam Sunder, the concave bowing of the steel was seen on the sides of the towers opposite where the planes hit them. At 10:06 a.m. that morning, an officer in a police helicopter reported that ``it's not going to take long before the north tower comes down.'' This was 20 minutes before it collapsed. In another radio transmission at 10:21 a.m., the officer said he saw buckling in the north tower's southern face, Shyam Sunder said."

"Engineers believe the bowing of the exterior steel beams near the flame-engulfed floors was the critical "triggering point" because that's the direction each tower tilted as it came crashing down."

"The report includes photographs taken from police helicopters showing the bending columns."

Key word....According to Shyam Sunder

No ... I'm calling you a liar. Quintiere is not a 9/11 foil-hatter and specifically said he is not a supporter of theories that the Twin Towers were brought down by pre-planted explosives but rather he had problems with NIST's research methodology. Quintiere, who left the NIST back in the 1990s (well before the 9/11 attack on America by your Jihadi brethren) never said their "forensic testing of wtc steel showed no signs of the temperatures sufficient to weaken steel" as you claim. As already mentioned, your lying is necessitated by the fact that the truth just doesn't support your CT silliness. Quintiere has had 8 years to substantiate his doubts about the NIST report. Do you have any follow up studies or scholarly papers on the matter from the good doctor?
Here are the pesky answers to your questions that were published well after his doubts.

Questions and Answers about the NIST WTC 7 Investigation

How did the fires cause WTC 7 to collapse?
The heat from the uncontrolled fires caused steel floor beams and girders to thermally expand, leading to a chain of events that caused a key structural column to fail. The failure of this structural column then initiated a fire-induced progressive collapse of the entire building.

According to the report's probable collapse sequence, heat from the uncontrolled fires caused thermal expansion of the steel beams on the lower floors of the east side of WTC 7, damaging the floor framing on multiple floors.

Eventually, a girder on Floor 13 lost its connection to a critical column, Column 79, that provided support for the long floor spans on the east side of the building (see Diagram 1). The displaced girder and other local fire-induced damage caused Floor 13 to collapse, beginning a cascade of floor failures down to the 5th floor. Many of these floors had already been at least partially weakened by the fires in the vicinity of Column 79. This collapse of floors left Column 79 insufficiently supported in the east-west direction over nine stories.

The unsupported Column 79 then buckled and triggered an upward progression of floor system failures that reached the building's east penthouse. What followed in rapid succession was a series of structural failures. Failure first occurred all the way to the roof line-involving all three interior columns on the easternmost side of the building (79, 80, 81). Then, progressing from east to west across WTC 7, all of the columns failed in the core of the building (58 through 78). Finally, the entire façade collapsed.

why do paste a summary of the wtc 7 collapse ? you probably do not even understand. according to NIST a kid with a pack of matches could cause the collapse of wtc 7 Quintiere without quesrion states NISTs forensic testing of wtc steel showed no signs of the temperatures sufficient to weaken steel and I provided the link btw ..you seem to be confusing the towers with wtc 7

Once again you spin like a whirling dervish and there is absolute evidence that the WTC fires, coupled with the impact of a large, fast moving passenger plane were sufficient to weaken the steel supports. Additionally you failed to address the difference between your silliness and Dr Quintiere's frustration with NIST methodology ... he, like me, finds your pre-planted explosives theory to be CTBS. BTW, fully 8 years have passed since his comments. Do you have any scholarly studies performed by Quintiere which prove or disprove his 2007 doubts?

NIST methodology was completly flawed dr Q was correct... there was no evidence of temperatures required in forensic testing to initiate failure... and again he is correct.. drQ made no direct statement on pre-planted explosives theory to be CTBS that was an editoral comment by the writer and not in quote however... Quintiere did say...Dr. Quintiere, one of the world’s leading fire science researchers and safety engineers, also encouraged his audience of fellow researchers and engineers to scientifically re-examine the WTC collapses. “I hope to convince you to perhaps become 'Conspiracy Theorists', but in a proper way,”
and also said...
“In my opinion, the WTC investigation by NIST falls short of expectations by not definitively finding cause, by not sufficiently linking recommendations of specificity to cause, by not fully invoking all of their authority to seek facts in the investigation, and by the guidance of government lawyers to deter rather than develop fact finding.
And also said...
Dr. Quintiere said he originally “had high hopes” that NIST would do a good job with the investigation.“They’re the central government lab for fire. There are good people there and they can do a good job.But what I also thought they would do is to enlist the service of the ATF [Bureau of Alcohol, Tobacco, Firearms and Explosives], which has an investigation force and a laboratory of their own for fire.And I thought they would put people out on the street and get gumshoe-type information.What prevented all of this?I think it’s the legal structure that cloaks the Commerce Department and therefore NIST.And so, instead of lawyers as if they were acting on a civil case trying to get depositions and information subpoenaed, those lawyers did the opposite and blocked everything.”

Did you listen to the recording, as it says the Steel was melted. That takes a temperature of about 3000 f ( 1500 c ). The experts talk of lumps of molten steel fused with concrete being found. They then show you a steel beam bent into a semi circle and you can see the valence bond failure points, they look like knife cuts in the steel.

You are full of shit and don't know what you are posting

correct..yet NIST asserts it never existed
the test they release shows no such temperatures existed in the tested steel
as dr Q correctly states ..but there is of evidence molten steel ..these were ignored as there is reasonable explanation for such excessive heat

He neither said nor inferred that "NIST methodology was completely flawed" but rather that the WTC investigation fell short of his "expectations." Quintiere is not a 9/11 foil-hatter and specifically said he is not a supporter of theories that the Twin Towers were brought down by pre-planted explosives.The question here is why must you always lie? Can it be that the truth just doesn't support your Jews-did-it lunacy?

never said.. jews did it

Sure you have and why else would you be posting your 9/11 CT silliness on the "If It's Bad.....Jews Did It" thread?
