15 Years Later: On The Physics Of High-­Rise Building Collapses

September 1st, 2016 Posted in | No Comments »

Screen Shot 2016-09-01 at 9.59.45 AMA new article by Steven Jones, Robert Korol, Anthony Szamboti and Ted Walter has just been published in the August edition of Europhysics News

In August 2002, the U.S. National Institute of Standards and Technology (NIST) launched what would become a six-year investigation of the three building failures that occurred on September 11, 2001 (9/11): the well-known collapses of the World Trade Center (WTC) Twin Towers that morning and the lesser-known collapse late that afternoon of the 47-story World Trade Center Building 7, which was not struck by an airplane. NIST conducted its investigation based on the stated premise that the “WTC Towers and WTC 7 [were] the only known cases of total structural collapse in high-rise buildings where fires played a significant role.”

Screen Shot 2016-09-01 at 10.30.07 AMIndeed, neither before nor since 9/11 have fires caused the total collapse of a steel-framed high-rise, nor has any other natural event, with the exception of the 1985 Mexico City earthquake, which toppled a 21-story office building. Otherwise, the only phenomenon capable of collapsing such buildings completely has been by way of a procedure known as controlled demolition, whereby explosives or other devices are used to bring down a structure intentionally.

Although NIST finally concluded, after several years of investigation, that all three collapses on 9/11 were due primarily to fires, fifteen years after the event, a growing number of architects, engineers, and scientists are unconvinced by that explanation.

Boston Globe Publishes AE911Truth Letter to the Editor

Evidence still raises questions over World Trade Center collapses

BostonGlobe

BostonGlobe.com

ALEX BEAM’S portrayal of “architect truthers” is yet another disappointing example of a journalist resorting to ad hominem attacks and avoiding the facts when discussing the destruction of the three World Trade Center skyscrapers on Sept. 11, 2001 (“The ‘truthers’ and 9/11,” Opinion, Nov. 16).

Sadly, not one sentence of Beam’s column examines the evidence for or against the controlled demolition of the Twin Towers and WTC Building 7. Instead, he devotes 600 words to revealing his own ill-founded bias.

He cherry-picks the appearance of three nonexperts from the 15-minute video “Architects & Engineers — Solving the Mystery of Building 7,” but doesn’t highlight any of the film’s “various experts.” Noting that some Americans think that what happened that day hasn’t “been fully explained,” he declares, “I don’t agree,” but gives no evidence-based reason for disagreeing. His position rests on his revulsion at the idea that someone — “our own government,” he supposes — consciously demolished the World Trade Center.

As building professionals, we at Architects & Engineers for 9/11 Truth try not to let personal feelings interfere with investigating the three worst structural failures in modern history. Nearly 2,400 architects and engineers, not including the 109 who signed our petition at the recent annual trade show ABX, have joined us because we stick to science.

The physical evidence shows that scattered office fires could not have caused the 47-story WTC 7 to collapse symmetrically into its footprint. (Imagine Boston’s 52-story Prudential Tower completely collapsing in seven seconds from small fires — it’s hard to, isn’t it?) The evidence also shows that the twin towers were not leveled by the airplane impacts and ensuing fires.

The implications are indeed far-reaching, and that is why we urge people to study all the evidence before reaching a conclusion.

Reality Check: Are More Americans “Rethinking” 9/11?

September 11th, 2013 Posted in | No Comments »

Ben Swann – Reality Check

September 10, 2013

Did you know that a 3rd building fell on 9-11?  That bill board is today over Times Square.  It was placed there through donations to a campaign called Rethink 9/11.

In fact, that group has placed posters and signs across the world, from Australia, to Canada, from San Francisco to right here in New York City.

So what is Rethink 9/11?  Wouldn’t only a fringe group of people would still question 9/11?  Perhaps not, because today we will tell you about new polling that shows a majority of those polled either question the official 9/11 story or don’t believe it at all.  Is that possible?

The first step toward truth, is to be informed.

Here in New York City, today at the site of the 9/11 Memorial, promises to never forget what happened the morning of September 11th, 2001.  But never forgetting doesn’t mean that you don’t rethink what you have been told.

Rethink 911 is the first ever global 9/11 anniversary campaign. Sponsored by a coalition of more than 40 organizations, ReThink911 is placing ads in 11 major cities around the world this September 2013.

But what is there to rethink? According to a group called Architects and Engineers for 9/11 Truth, you need to start by rethinking the third building that fell that day.

Building 7,  behind me.   That rectangular building is the new building 7.  It stands a little smaller but in the same place where the original World Trade Center 7 once stood.

To be fair, the collapse of building 7 has long been the claims of conspiracy theorists. In 2008, the National Institute of Standards and Technology or (NIST) released its long-awaited report on the collapse of World Trade Center 7.  The lead investigator Shyam Sunder told journalists,  “WTC 7 collapsed because of fires fueled by office furnishings. It did not collapse from explosives or from diesel fuel fires.”

But that claim has been taken on by that rapidly growing group known as Architects and Engineers for 9/11 Truth.

Rethink 911

Today, more than 2,000 progressional architects and engineers from around the world have joined together to say that the NIST claim that Building 7 came down because of office fires is not only untrue, it is not possible.  That no skyscraper in history has ever come down that way.

That the way Building 7 fell was without the building tipping or rocking and that in order to fall like this, a building could only come down IF all the internal columns supporting building were to give way at the same time.

Enginneering is a technical field but most of us would know this as a controlled demolition.

To better understand the claims of AE for 9/11 Truth, I talked with Tony Szamboti, a mechanical design engineer with 27 years of experience in the aerospace and communications industries and one of the 2,000 engineers calling for an a new, independent investigation of the collapse of Building 7 and the World Trade Center towers.

Swann:  “So you look at this image of the building falling, again NIST says that its office fires that have caused this.  You say.. ‘give me another example?’”

Szamboti:  “There is no other example.”

Swann:  “No other example in the world?”

Szamboti: “They have no other example,”
Swann:  “So this has never happened?  This would be the first building in the world to come down this way?”

Szamboti: “And they say that.  They say that thermal expansion caused it.  What I say caused it and you can cut this out or leave it in, but I think they took out the core columns for 8 full stories, and that pulled in the exterior.  When you have controlled demotion, and when take the core out, you pull in exterior and it comes down.  When you take out 8 stories it all comes in.”

Swann:  “What happens if you leave half of them?  If it is not a controlled demolition and you have a failure of some columns?”

Szamboti: “Then you have a partial collapse.”

And there is another issue of how NIST says Building 7 came down.  The say it was normal office fires.  The technical explanation is that floor beams expanded because of heat and ultimately pushed a single column, column 79 off of its seating.  That, NIST says, caused the entire collapse of the building.  But what NIST told the public in 2008 was the reason these columns were pushed loose is because they were unrestrained.

What was discovered last year in 2012 after a Freedom of Information Act (FOIA) request was granted, that claim was not true, that the columns were not unrestrained.  In fact there were 3,896 shear studs holding those columns in place.

Szamboti: “One is, the beams could not expand far enough and if they could expand enough, those stiffeners would stop that girder from falling off.  They were bonded.”

Swann: “But for the person that say, so you have so disagreements on some technical things.”

Some Misunderstandings Related to WTC Collapse Analysis

Received on 22 Dec 2012, Accepted on 8 March 2013

International Journal of Protective Structures – Volume 4 · Number 2 · 2013

ABSTRACT This article elaborates on variables associated with the collapse of the North Tower of the World Trade Center. The previously published quantifications of inertia, column capacity, and the assumptions related to the beginning of downward motion, are examined and corrected. The reasons for false conclusions reached in several previous analyses are presented.
Key words: Large Deflections, Plasticity, Collapse

1. INTRODUCTION This presentation is not so much about how the WTC towers failed, but about how they could not fail. The objective is to eliminate erroneous concepts supported by false assumptions and by the use of incorrect values for velocity, mass, and column resistance. The only complete hypothesis of the global collapse mechanism of the Towers is a successive flattening of stories associated with compressive column failure and referred to as a Progressive Column Failure mode or PCF in brief. (In the past this mode was often referred to as pancaking, but this term is not used here to avoid ambiguities). It is explained here why PCF could not be the mode of the ultimate destruction. The previously published material is quoted and the new points are brought up. Appendix C can be of interest to those who want a broader description of facts associated with the collapse. The available information relating to the kinetics of the collapse is summarized first.

As 9/11 Continues to Justify State Crimes, New Book Reveals Suspects: “Another Nineteen: Investigating Legitimate 9/11 Suspects”

June 23rd, 2013 Posted in | No Comments »

Global Research, June 14, 2013

The U.S. government has turned to 9/11 again in order to justify its program of spying on all Americans and to support a new, expanded war in Syria. Yet as Americans are distracted by these ongoing crimes, the deception behind the origin of the War on Terror is being more fully revealed.

Were the crimes of September 11, 2001 solely the work of Osama bin Laden and nineteen troubled young Arabs, or were more powerful people involved? After a decade of investigation Kevin Ryan, the co-editor of the Journal of 9/11 Studies, offers an evidence-based analysis of nineteen other suspects.

Cover2C With the support of victim’s families and leading 9/11 researchers, Another Nineteen looks at who was in position to accomplish major elements of the crimes that have yet be explained. Detailed evidence is presented that reveals how each of the alternative suspects had the means, motive and opportunity to accomplish one or more aspects of the 9/11 attacks.

“Finally a comprehensive and meticulously researched book that thoroughly details what occurred before and on 9/11. Without a doubt, Another Nineteen should be required reading for those who want the real story.” – Robert McIlvaine, father of Bobby McIlvaine, who was killed at the World Trade Center on 9/11

“Kevin Ryan has written a book that reminds us that the attacks of September 11, 2001 and their details have never really been investigated. Kevin has laid out the historical framework in a way that has never been done before. The importance of this cannot be overstated.” – Lorie Van Auken, member of the Family Steering Committee for the 9/11 Commission and widow of Kenneth Van Auken, who was killed at the World Trade Center

Starting with what should have happened that did not, and what should not have happened that did, Another Nineteen reveals that certain powerful people had the means, motive and opportunity to make 9/11 happen exactly as it did. Those people represented private networks and government programs that came together in surprising ways on 9/11.

To get the book, go to the secure E-store: https://www.createspace.com/4289114 or look for it on Amazon (by June 21).

New Website for Scientific Discussions, and a New Paper on the Pentagon

March 26th, 2013 Posted in | No Comments »

A new website, www.scientificmethod911.org is now up and running. Its primary purpose is the discussion of scientific papers on the events of 9/11. In order to maintain dialog at the level of principles inherent in the scientific method, the discussions will be moderated. After evaluation, comments and responses will be posted on the website in a discussion page. Authors are invited to submit their writings, both old and new, for discussion and feedback from the wider community of 9/11 researchers. Send papers to moderator@scimethod911.org. The community at large is invited to read the listed papers and provide comments and feedback.

A new paper is now available:

The Pentagon Attack: The Event Time Revisited,” by John D. Wyndham.

From the abstract:

“Since publication of my paper, “The Pentagon Attack: Problems with Theories Alternative to Large Plane Impact,” questions have arisen about some statements made therein, specifically those concerned with the clock evidence for the event time. This paper reviews the evidence and finds that it is much more convincing for an event time around 9:38 am than for a proposed earlier time around 9:32 am. It is shown, by experiment, that the minute hand of the Heliport clock could easily have moved from a time around 9:38 am back to a time around 9:32 am because of the abrupt deceleration that occurred when the clock hit the ground after falling off the wall.”
