However, everything else was correct. A simple office fire CAN reach temps in excess of 1400f. You can see it quite plainly in the Madrid Tower fire. All the steel above the 2nd technical floor, laying in the street, 3 hours into a fire that grew from a single ignition point. No plane. No kerosene fuel. Just office crap.
All you have to do is get that ATSM steel to its self tempering temperature, or close to it. It rapidly loses strength as you do. Deduct load capacity from the missing beams, weaken the rest with heat...
The outcome is inevitable.
The hot rubble pile is inevitable.
All of this is normal. There is nothing strange about the rubble being hot. There is nothing strange about the collapse. There is no extra energy to account for.
