I will have to do a SLC post on this when I get a chance, but I figured you guys would want a head start.

Recently, Anders Björkman, an independent structural engineer from Europe, has written a response to the conclusions of Zdenek Bazant of Northwestern University about what caused the collapses of the World Trade Center.
Björkman, a Swedish naval architect and engineer, has exposed the biggest fraud in maritime history behind the 1994 sinking of the Baltic ferry Estonia. Now he has joined the discussion about the demolition of the World Trade Center with an article in which he does a good job of disproving Bazant's "false theory" that burning jet fuel brought down the twin towers.
Björkman's article was written for "children and amateurs of skyscraper design who want to get a better understanding of the world around us."
He "describes the structure of the World Trade Center Twin Towers and what happens when the release of potential energy, due to downward movement of the mass above one of its supporting columns when buckling, exceeds the strain energy that can be absorbed by the same column below."
He concludes that "no global collapse of the Towers can ensue under the given circumstances." He even describes a simple test that can be done to see how the steel in the towers would have responded to the 500 degree C. heat it was exposed to.
You can find the link to the Swedish "structural engineer" (naval engineer actually) in the article. For some reason rather than submitting it for review, he posted it on a free tripod webpage.
