molten metal is one of the keys to the truth shack. "flare ups" because of "exposure to oxygen" caused it? like, why would this cause temperatures FAR in excess of the hydrocarbon fueled fires which burned freely for over an hour?

Wind speed increases with elevation, which is why top of hills are windy
considering enormous holes blasted into sides of building by aircraft
impact wind blowing through holes would fan fires. Ever blow on
a fire? The increased oxygen flow causes the fire to flare up.
Wind blowing on WTC fires would quickly fan them into blast furnace
intensity.

Chapter 4.2 is titled Impact energy to collapse 1 WTC floor. It includes calculations for the core and exterior columns...... an estimate of 6.29x10(8)J is required to collapse one floor....... This isn't what you were looking for?
Unfortunately there appears to be no simple way to calculate E1 from first
principles since the collapse of just one floor of a WTC tower is an extremely complex process involving the bending and fracturing of numerous support structures.
In spite of these uncertainties, some estimates of the magnitude of E1, (the energy needed to bring about the collapse of one floor), have been made. For example, Z. Bažant et al. at Northwestern University, Illinois, have estimated that the maximum plastic energy dissipated by the collapse of one floor, i.e. our quantity E1, is approximately equal to 5.0 x 10^8 J. Unfortunately Bazant et al. do not give a detailed exposition on how this value for E1 was derived, stating only that it is based on “approximate design calculations”
However, it appears that Lee’s results are based on very rough estimates of the energies involved
These authors have calculated the energy dissipated by the wing of a Boeing 767 cutting through the exterior columns of a WTC tower and report a value equal to 1.139 x10^6 J per column. On this basis, 2.69 x10^8 J would be require to cut through all 236 exterior columns supporting one WTC floor.
