 SEC. 1021. AFFIRMATION OF AUTHORITY OF THE ARMED FORCES OF THE UNITED STATES TO DETAIN COVERED PERSONS PURSUANT TO THE AUTHORIZATION FOR USE OF MILITARY FORCE.
WTC1 and WTC2 destroyed first
As reported by the New York Times, NYT, on 9/12/2001:  It is suggested that jet planes hijacked by some young Arabs destroyed (!) the NY WTC 1 and 2 twin towers September 11, 2001! It was fake news!
To suggest that the buckling of one pillar/column between two or more floors will initiate failures of columns upwards, sideways and downwards leading to global collapse of the complete structure is ... ridiculous! On Internet you find plenty footage videos/photos, e.g. this (fake) video, of the complete, intact, horizontal top part/roof of WTC7, not hit by any plane, suddenly dropping down behind intact buildings. How could it happen? The perfectly symmetrical and total collapse of three commercial high rise office buildings on 11 September 2001, WTC1, WTC2 and WTC7 can only be explained as controlled demolitions, requiring a considerable amount of advance planning, preparation, expertise and access.
"WTC7 was prone to classic progressive collapse (sic!) in the absence of debris impact and fire-induced damage when a section of column #79 between Floors 11 and 13 was removed. The collapse sequence demonstrated a vertical and horizontal progression of failure upon removal of the column #79 section, followed by buckling of exterior columns, which led to the collapse of the entire building." As a non-regulatory (criminal, terrorist!) agency NIST can of course invent anything, e.g. "a vertical (?) progression of floor failures" up to the roof took place or "an east to west horizontal progression of interior column buckling" followed. But why wood 30 intact floors suddenly fail? The floors do not support the structure. They just carry load to the columns. Or did all the columns fail. Each interior column is laterally supported by four beams/girders. Did all four beams/girders disconnect allowing that 23 intact interior columns suddenly buckled? No, it is not possible. But according NIST it was the first time in history, that fire caused the sudden and complete collapse of a large, fire-protected, steel-framed building on 9/11, when one structural member - column #79 - initially failed, when a floor girder #A2001 was disconnected from column #79, so it lost support and buckled. A professor from the University of Alaska, Fairbanks, Dr. Leroy Hulsey, has examined the NIST WTC7 report and done his own FEM/beam model of the structure and he concluded 6 September 2017 the results of his preliminary findings that "WTC 7 Did Not Collapse from Fire"! Klick on the link and listen to his presentation. It seems Dr. Hulsey hasn't heard about redundancy or "the inclusion of extra components, which are not strictly necessary to functioning, in case of failure in other components". Fact is that no structure or building can ever globally collapse due to local failure of one element - a vertical column - or connection - beams/girders - inside the structure e.g. due to thermal expansion. It is easy to show! Just remove the complete critical member - column #79 - between floors #6 and #13 (or whatever) in any FEM/beam model of the structure and see what happens! I do it below! There is no collapse! Only adjacent structural members are higher stressed. Redundancy! Only terrorists think buildings collapse, when one member fails. Unfortunately Dr. Hulsey hasn't yet done this experment, but it is easy to do. The FEM/beam model of the structure is available. Just re-run the model without column #79. There exists in structural damage analysis theory no phenomenon as 'classic progressive collapse'! It is just a stupid invention by a non-regulatory, criminal terrorist agency like NIST, as follows: "Progressive collapse is defined as the spread of local damage (? - failure!) from a single initiating event, from structural element to element, eventually resulting in the collapse (? - failure!) of an entire structure or a disproportionately large part of it. The failure of WTC7 was an example of a fire-induced progressive collapse." It is supposed to have happened for the first and only time in History on 911. But it is just a Great Deception! The one major tenant of WTC 7 was Salomon Smith Barney (SSB), the company that occupied 37 of the 47 floors in WTC 7. A little discussed fact is that Rumsfeld was the chairman of the SSB advisory board and Dick Cheney was a board member as well. Rumsfeld had served as chairman of the SSB advisory board since its inception in 1999. According to the financial disclosures he made in his nomination process, during the same period Rumsfeld had also been a paid consultant to the Director of Central Intelligence, George Tenet. Rumsfeld and Cheney had to resign from their CIA and SSB positions in 2001 when they were confirmed as members of George W. Bush's cabinet. Imagine that a US vice president and a US secretary of War had rented 75% of a building that suddenly just ... collapsed ... soon after they joined the government. What kind of terrorism is that? Redundancy always ensures that one local, structural failure will not destroy the complete or entire structure and all its elements/joints. That is the reason why nobody will ever win the €1M Anders Björkman Challenge 1! NIST is evidently producing fake definitions and reports in support of criminal, US terrorism! NIST is part of the US terrorist network, I am sad to conclude. Below will be explained in detail how and why NIST produces a fake report. WTC7 was a very simple steel structure and not prone to any classic progressive collapse of any kind, whatever it means. There were 24
inner
columns/pillars #58-81
supported by
26
external wall columns
as per simplified figure right. The vertical
columns/pillars were primary load
carrying parts connected to ground. The columns
were connected by
horizontal
beams/girders at every
floor providing lateral support. The beams/girders
were secondary load carrying parts
carrying local floor loads to the
primary parts - the vertical
columns. The floor panels,
tertiary parts, are then
resting on the beams/girders, like the external
wall panels connected to the external columns.
There were 47 floors. Total height of structure was
147 meters. A more detailed animation of the
structure can be seen here
and a full description here!
It is a VERY STRONG structure! The
horizontal
beams/girders
(secondary structure) carrying
the floor panels transmit average about 200
tons (50 tons each) of weight to an
inner
column at every floor
and 50 tons of weight to a
wall
column. You
evidently have to adjust the actual load for
different spans of beams, floor areas, unusual
static loads, etc. It means that the
total load transmitted to the ground by
each
inner
column is on average
9 400 tons. A
wall
column transmits one
quarter that load to ground or 2 350 tons.
Again the real values have to be adjusted for
actual values of loads transmitted to the columns
from the beams. The columns have variable
dimensions/materials from ground to roof so that
the compressive stress is always
<30% yield at every floor level. Evidently the
bottom columns are much stronger than the top ones.
The bottom column/pillar is 47X stronger than
the top column below the roof! Note that the
inner
columns/pillars carry
abt. 81% of the total load in this simplified
model. The maximum combined stress in
any horizontal beam/girder is also <30% yield.
The dimensions of the beams (adjusted for span) are
similar everywhere as they only carry
local loads. The floor panels are
just thin structures carrying load to the beams. In
figure right we see that an
inner
column is removed
between floors 11 and 13 adjacent to two
wall
columns. It is similar
to column #79 in WTC7. The load carried by that
inner
column above floor 13
is, say,
6.800
tons and evidently the adjacent
inner
columns carry the same
load - 6 800 tons. The adjacent
wall
columns carry one
quarter that load - 1 700 tons. The result is as
follows: The load in an adjacent
inner
column increases from
6.800
to
8.500
tons and the load in an adjacent
wall
column increases from
1.700
tons to
3.400
tons or the local compressive stresses
increase 25/50%. As the stresses in the adjacent
columns were <30% yield before removal of the
column, the stresses are now still only
<37.5/45% yield, i.e. well below any critical
value. In reality there are more wall columns than
shown in this simplified model, which are
interconnected, so the load is shared between them.
The bending stresses in the
horizontal
beams above the removed
column part will double, which is still <60%
yield. It means that nothing will really happen to
the complete structure except that named parts
become a little more stressed. There will be no vertical
progression of failures due to removing one part of
an
inner
column! To suggest,
like NIST, that the whole structure collapses
progressively is criminally absurd! It can be noted that the load at
ground of the
inner
columns carrying the
extra load of the removed column increases from
9.400
to
11.100
tons or only 18%. Similar happens to the adjacent
wall
columns. Removing a
column 'X inside a structure will not produce
'global or progressive collapse' of the
entire structure below and above! The load
previously carried by the column will simply be
transmitted to adjacent
columns
via the horizontal
beam elements above
the failed column and down to ground =
redundancy! Horizontal
elements just
above the removed column will
rotate/displace down but are retained by intact
connections/elements. What is real structural damage analysis to simulate a collapse (or for that matter, a high energy ship collision)? It is 1000's of (static) analysises, where each phase of damages/failures development is analysed separately with the modified input of structural arrangements and loads applied due to damages of the previous stages. You evidently start with an intact plate/stiffener structure, then identify the first failure (a cracked plate?), then redo the analysis of the complete structure with that failure and modified loads to identify the second failure (a ruptured stiffener), etc. The purpose is to establish a path of failures through the structure. At each stage the energy consumed to produce the failure is calculated and is deducted from the energy available to drive the destruction. Released energy due to failures or still applied from outside is evidently added. NIST might have tried to do just that, e.g. divided the structural 'collapse' into say 6500 of 1/1000 seconds intervals and run 6500 static models, each one representing the status of the structure during the alleged 6.5 seconds collapse with failed parts, modified load patterns, modified structure, etc, and uploaded and included it in the new model at every stage, but there is no indication that they did it. There are too much manual manipulations involved unless you have a clever software to do it ... which as far as this writer is informed NIST does not have as it does not exist! This is confirmed by correspondence 14-15 January 2009 between Mr. Geoffrey Walter Ritchey and NIST: I respectfully request copies of the following NIST records: I assume Mr. Ritchey simply wanted to see the intact, loaded model with no failures and then remove the famous column #79 below floor #12 to see what happened, i.e. nothing, except that adjacent columns were more stressed. The response from UNITED STATES DEPARTMENT OF COMMERCE National Institute of Standards and Technology, NIST, was simple: NIST has no documents that are responsive to your request. However, NIST had the documents and made them secret because later we are told the following: Structural Analysis Input used for the Damage Analysis made secret!! http://cryptome.org/nist070709.pdf As director of a non-regulated agency like NIST Patrick Gallagher can of course invent anything and produce whatever lies he likes. It would appear Patrick Gallagher supports terrorism! So NIST has made secret the evidence for the following amazing damage analysis results - including analysis of a big free falling structure with no internal loads acting on it :  The report includes figures 3.10-13
showing the right side with pillars/columns
#79-81 collapse below floor 16 (?) at 0.5, 2.5
(shown above), 4.5 and 6.5 seconds, while the
left side with pillars/columns
#58-78 remains intact. Apparently everything above
pillars/columns #79-81 drops down due to
vertical failures' progression - there are
free-flying parts! But the remainder of the
structure below floor 16 with pillars/columns
#58-78 is just locally damaged during 6.5
seconds. Nothing drops down from below = there is
no free debris there. You would then expect the
upper, intact part to tilt to the right! The horizontal failures'
progression is not clear. What
energy is required to produce all
these failures? NIST does not provide any
data. Then there is the whole, intact,
undamaged part above floor 16 - the upper intact
part of WTC7 above floor 16. How to handle
it? Upper 31 Floors Part of WTC7
free fall drops for 2.25 Seconds  The 'finding' is however based on measurements from a video and there is no evidence that the video is real and no scientific analysis of the origin of the video has been made. The video could be simple Computer Generated Images, CGI, and the acceleration of the CGI roof line just copy & paste of any free fall drop on Earth. That the complete top of any wide structure below pillars/columns #58-81 free fall drops on a video is a very strong indication that the video is fake, as no such big part of any structure cannot free fall drop, unless subject to demolition from below.
"Computer simulations of … the structural collapse can be used to predict a complex degradation and collapse of a building", has no foundation in the case of WTC7. It is a lie! NIST has not done a correct job! The WTC7 structure does not collapse as shown in figures 3.10-14 due to removing a part of pillar/column #79 as a local failure. Quite easy for anybody with basic knowledge of structural damage analysis to verify! When a structure is free fall dropping no internal forces act on the elements in the structure. The video is a fake.
An explanation how the 24 inner pillars/columns #58-81 below floor 14 could suddenly 'disappear' simultaneously to produce the confirmed 32.77 meters free fall of the structure above is given here. The inner pillars/columns #58-81 between floors 6-13, carrying 81% of the total load, simply 'evaporated' at two locations or floor levels due to a compound applied to them that burnt extremely quickly! The load carried by the inner pillars/columns #58-81 was then transmitted to the wall columns! The wall columns floors 6-13, which previously carried only 19% of the load, now carry 100% of it and cannot resist and buckle inward - they are pulled in by the floor beams! - as can be seen in the rubble. It explains the complete lack of parts of these lower inner columns in the rubble and also the presence of molten steel there and very strange looking pieces of junk! Further thoughts about this matter can be found here.
Actually, every essential piece of information in the NIST WTC7 report is fake and misleading. NIST does not explain the collapse at all! The report is just a description of a massive amount of local failures that would not occur in the first place (due to lack of potential energy produced by gravity alone) and no global total collapse at any speed would or could follow as suggested by NIST. ASCE, the American Society of Civil Engineers, has a Code of Ethics that the NIST staff should follow: Fundamental Principles It is clear that NIST does not follow these principles! NIST is actually a criminal organisation supporting terrorism. And nobody seems to care ... except AE911truth.org !
