Public safety paradox

http://www.seaonc.org/pdfs/SEAONC_September_2010.pdf

September 2010

Dear Editor:

The complete collapse of World Trade Center Building 7 (WTC 7) was highly anomalous—that's why it is critical for building design and construction professionals to understand it. Freedom of Information Act requests for structural-analysis data have been denied because the National Institute of Standards and Technology (NIST) Director determined that release of the data might jeopardize public safety. I asked the Director:

How, in the Director's judgment, is the release of calculations and analysis results—developed at the taxpayers' expense for a building that no longer exists—a threat to public safety?

His response was:

The decision to withhold the data was based on the fact that the capabilities of the WTC 7 collapse initiation and global collapse models are unprecedented, in that they provide validated models that can predict collapse of typical tall buildings. If released, these models would provide a powerful tool to groups and individuals interested in simulating building collapses and devising ways to destroy buildings.

This response from NIST is an insult to building design and construction professionals who are committed to ensuring public safety with high-quality construction. As a structural engineer I have a professional interest in understanding the collapse, and it has nothing to do with ''devising ways to destroy buildings." If the WTC 7 models actually predict the complete collapse of typical tall buildings subjected to office fires, then withholding this information is not in the interest of public safety.

Independent verification is an integral part of science, so I strongly encourage the NIST Director to reconsider his decision to withhold analysis data. Only independent verification will enable these complex models to be validated.

Sincerely,

Ronald H. Brookman, SE

WTC Building #7, a 47-story high-rise not hit by an airplane, exhibited all the characteristics of classic controlled demolition with explosives:

Rapid onset of collapse
Sounds of explosions
Symmetrical structural failure
Free-fall acceleration through the path of what was greatest resistance
Imploded, collapsing completely, landing almost in its own footprint
Massive volume of expanding pyroclastic-like clouds
Expert corroboration from the top European controlled demolition professional
Foreknowledge of "collapse" by media, NYPD, FDNY

In the aftermath of WTC7's destruction, strong evidence of demolition using incendiary devices was discovered:

FEMA finds rapid oxidation and intergranular melting on structural steel samples
Several tons of molten metal reported by numerous highly qualified witnesses
Chemical signature of the incendiary thermite found in solidified molten metal, and dust samples

WTC7 exhibited none of the characteristics of destruction by fire:

Slow onset with large visible deformations
Asymmetrical collapse which follows the path of least resistance (laws of conservation of momentum would cause a falling, to the side most damaged by the fires)
Evidence of fire temperatures capable of softening steel
High-rise buildings with much larger, hotter, and longer lasting fires have never collapsed

As seen in this revealing photo, the Twin Towers' destruction exhibited all of the characteristics of destruction by explosives:

Destruction proceeds through the path of greatest resistance at nearly free-fall acceleration
Improbable symmetry of debris distribution
Extremely rapid onset of destruction
Over 100 first responders reported explosions and flashes
Multi-ton steel sections ejected laterally
Mid-air pulverization of 90,000 tons of concrete & metal decking
Massive volume of expanding pyroclastic-like clouds
1200-foot-diameter debris field: no "pancaked" floors found
Isolated explosive ejections 20–40 stories below demolition front
Total building destruction: dismemberment of steel frame
Several tons of molten metal found under all 3 high-rises
Evidence of thermite incendiaries found by FEMA in steel samples
Evidence of explosives found in dust samples

The three high-rises exhibited none of the characteristics of destruction by fire:

Slow onset with large visible deformations
Asymmetrical collapse which follows the path of least resistance (laws of conservation of momentum would cause a falling, intact, from the point of plane impact, to the side most damaged by the fires)
Evidence of fire temperatures capable of softening steel
High-rise buildings with much larger, hotter, and longer-lasting fires have never collapsed
