Fireproofing or not, it makes absolutely no difference. It is simple physics that jet fuel can not burn hot enough to melt or weaken steel. Combine that with the sheer size of the core columns, and the number of them, aswell as the conduction of heat away from zone of heating.. and you have yourself a bogus simulation.
That is all irrelevant anyway once you come to realise the simple truth that no planes hit the towers..
Aluminium planes can slice through steel box columns like butter.. Jet fuel fires can weaken high grade steel.. A pancake collapse can pulverize 99% of the building into micron fine powder.. And still have enough energy left over to keep steel molten in the basement of the WTC for 100 days..
Hurray for cartoon physics!!
