While doing some research I found this interesting tidbit of information:
While conducting hydrocarbon fire tests for tunnels in Norway , Those that were conducting the tests achieved temps of 2480 degrees F (1360 degress
C.) This was off of just 396.25 gallons (1500 liters) of gasoline. Since jet fuel has a higher ingnition temp it will burn hotter than gasoline. So if
gasoline can achive temps hot enough to melt (or at least significantly weaken) steel.....JP4 can also since it burns hotter. Plus the structrual
members has their fire retardent stripped away in the intial impact, that just made them even more suseptable to failure.
Also found that nozzle temps of a jet engine can reach 2700 F ( 1482.22 degrees C ) at afterburn stage indicating to me that jet fuel can burn at
least 1000 F ( 537.77 degrees C ) degrees hotter than the 1500 F ( 815.55 degrees C ) degrees stated.
In the fire service we are taught to expect failure of steel members after the temps have reached 1000 degrees F (538 degrees C). Steel at that temp
has also been shown to elongate 4 inches or more, Now granted these are structural members as opposed to steel truss roofing, but any steel subjected
to the intence heat from the jet fuel and ordinary combustibles present in the building, that is missing it fire retardent coating, lasting for almost
a hour, carrying the loads that they were carrying, failure seems like a likelyhood to me.
I hope the link worked..I have not attempted such a feat before...lol
