Since you have a scientific background ... 1. Historically there are no cases for steel framed high rise multi-storey buildings collapsing after fire - think WTC7 i.e. not impacted by planes. 2. Consider melting point of steel is 1500 C Parametric office fires max. 1000 C 3. The USA or indeed any other national building codes have remained unchanged after the event. 4. Asymmetric fire sources don't lead to symmetric collapse. 5. WTC7 collapse was in free-fall i.e. not a progressive collapse. None of the above is particularly controversial. Best
