Peer reviewed documents explaining the WTC collapse


I see there has been a lot of discussion here questioning the NIST summary of the WTC collapse. Here's some light reading for all of the deniers, these are all peer-reviewed papers, studies, tests, and other documents by experts in the field that explain and support NIST report. Again, I am still looking for anything from you that contradicts any of this.

These are focused on analysis & modeling of progressive collapse.

This first book is great. It's a structural engineer's explicitly discusses the analysis of progressive collapse of tall buildings, and includes a specific section on the WTC towers.

It’s a little pricey, and you cannot download it. You have to read it on-line.

Papers that support NIST, Bibliography, Engineers’ info on collapse


And this one is superb. It discusses new ways that structural engineers have been generating, since 9/11, in order to analyze collapse of buildings.

Dominant Factor in the Collapse of WTC-1
Konstantinos Miamis, Ayhan Irfanoglu, and Mete A. Sozen
Journal of Performance of Constructed Facilities Aug 2009, Vol. 23, No. 4, pp. 203-208

The behavior of the World Trade Center Tower 1 on September 11, 2001 is studied in light of experimental data on the effect of elevated temperature on mechanical properties of structural steel. It is concluded that the damage inflicted by aircraft impact on the insulation of the core framing was the dominant factor in the collapse of the structure.

1. Introduction
Structural engineers have a responsibility for incorporating fire safety into their building designs in order to minimize loss of life and property. The collapse of the twin towers of the World Trade Centre in New York was a reminder of the potential of fire to cause devastating failures of high-rise buildings by initiating progressive collapse.

Not that any "truthers" will read this or care, but also evidence that a plane went into the Pentagon are surviving rescuers who witnessed airplane parts in the building.

superstarlet you make sense and take note of the incontrovertible truths of 9/11....you must not be a conspiracy theorist.

I'm not.
