I am curious to hear the voices of those who frequent this forum as to whether 4 to 4.5 hour fire simulation times are valid for WTC 7 studies such as those contained in the NIST and Weidlinger Associates analyses. The ARUP study used just one hour in its fire simulation.
We have all heard that the fires will burn up the fuel in any one area in about 1 to 2 hours maximum and also that the fires reach temperatures above 600 degrees C for about 40 to 60 minutes and then start to cool. This was shown in the Cardington test data.

It is also interesting that the Cardington test data for protected steel does not reach temperatures which would produce failure. WTC 7's steel was protected.
