The first published technical theory of the collapse of the twin towers was "Why Did the World Trade Center Collapse?—Simple Analysis", written within days of the disaster by Civil Engineers Zdenek P. Bazant1 and Yong Zhou. Based on a number of assumptions, particularly a hot prolonged jet fuel fire which raise the core columns to excess of 800C, this paper shows how the building would suffer global failure, following complete failure on a single floor.
