Not well known to debunkers or Cters, this was brought up as yet another explanation for how WTC 7 could collapse by fire alone. The full report can be found here: http://www.thorntontomasetti.com/projects/world_trade_center_7_collapse_investigation/ Link to PDF Excerpt: Ultimate Conclusions Based on our review of the record, independent analyses, engineering judgment and our thorough examination of plaintiffs experts reports and analyses, our main findings can be summarized as follows: 1. Our analyses establish that the attacks of September 11 resulting in the collapse of WTC 1 which showered flaming debris unto WTC 7 set-off an unstoppable and causal chain of events, given the circumstances of the day, of such magnitude as to exhaust the capacity of the building structural system over the course of seven hours leading to the ultimate collapse of WTC 7. 2. Under ordinary circumstances, WTC 7 would have been able to arrest a localized slab collapse from progressing into a total collapse of the building. Under the extraordinary circumstances of September 11, and the very specific fire distributions, extent and durations resulting from those attacks, the progression from the initiation to global collapse is entirely due to those events and could not have been prevented even if the alleged deficiencies had been addressed as proposed by the plaintiffs experts. Our determination of the response of WTC 7 to the various loads it was subjected to on September 11 until its ultimate collapse is consistent with the visual evidence recorded on September 11. It's unclear how much Richard Gage has taken into this into account, since it was released in Oct of 2010, and the narrative Gage sticks to is based on the Bentham paper fraud, released in 2008.
