Mechanical Engineer here, the temps reached as high as 2000 F. this increases the ductility of steel tremendously, the steel became very bendable at this temp and that is what led to the pancaking floors upon one another, after the intitial few floors fell, dynamic overloading took over on the remaining floors.
