“29 Structural/Civil Engineers Cite Evidence
for Controlled Demolition - Spiral Bound”

As of July 2010, more than 1,200 architects and engineers have joined the call by AE911Truth for a new investigation, faulting the official reports and documenting the explosive evidence for the destruction of the 3 WTC high-rises on 9/11. This exclusive 13-page article includes seven pages of fascinating interviews along with six pages of biographical info about 29, of over 60 total, structural/civil engineers who are extensively quoted in the article.

You’ll quickly get a sense of the easily and intuitively understood rational thinking that structural engineers are capable of once they are exposed to the evidence and have had a chance to digest it.  And you can use this article and the simplicity of the quotes from the engineers to sway your friends, engineers or not.

Regarding the mysterious collapse of World Trade Center Building 7, Kamal Obeid, S.E., ponders, “A localized failure in a steel-framed building like WTC 7 cannot cause a catastrophic collapse like a house of cards without a simultaneous and patterned loss of several of its columns at key locations within the building.”

The symmetry of collapse troubled Dennis Kollar, P.E. (licensed Professional Engineer in Wisconsin), “the totality and uniformity” and the fact that the mass of debris remained centered on the building core all the way down. The towers should have instead fallen “with increasing eccentricity as the collapse progressed,” writes Howard Pasternack, P.E. “These systematic collapses required that any structural connections not only fail ’nearly simultaneously,’ but also ’in sequential order,’” wrote Frank Cullinan, P.E., who designs bridges in Northern California. That’s “impossible from asymmetrical impact loading and small, short-duration fires.”

The structural engineers find it difficult to believe the government’s claim, scattered fires brought about such an orderly collapse. Failure of heat-weakened steel would show “large deflection, symmetric and local failure, and slow progress,” David Scott told colleagues at the Institution of Structural Engineers in the UK.

William Rice, P.E., a Vermont structural engineer, expects fire-induced failures to be “tilting, erratic and twisting.”

While Ronald Brookman, S.E., a licensed structural engineer from Novato, California, figures on “a partial collapse to the side”.

“Symmetrical collapse requires simultaneous failure of all supporting columns,” notes Charles Pegelow. “How could all 47 core columns fail at the same instant?” Pegelow has performed design work on offshore oil rigs and tall buildings. His opinion: “Fires could not do that.”
