What Caused Building 7s Collapse?
This question would appear to be the greatest in engineering history. In over 100 years of experience with steel-framed buildings, fires have never caused the collapse of a single one, even though many were ravaged by severe fires. Indeed, fires have never caused the total collapse of any permanent steel structure. What was done to answer this most important question? The only official body that admits to having investigated the curious collapse of Building 7 is FEMA’s Building Performance Assessment Team (BPAT), which blamed fires for the collapse but admitted to being clueless about how fires caused the collapse. People who have seen buildings implode in controlled demolitions are unlikely to be as challenged as FEMA’s team in understanding the cause of Building 7’s collapse. They will notice, upon watching the videos, that Building 7’s collapse showed all of the essential features of a controlled demolition. Despite having the appearance of a controlled demolition, is it possible th
