The Cardington Tests are not a meaningful comparison to the WTC fires since they involved a fuel load of 44 kg/m^2. NIST states quite clearly that the WTC fires were fed by 20 kg/m^2 fuel loads. The time vs. temperature profiles in the Cardington Tests were nothing like the equivalent profiles reported by NIST for the workstation fire tests. Also the section factors of the structural members exposed to the WTC fires were generally quite different to the section factors of the steel exposed in the Cardington Tests.
Let's compare apples with apples please.
