First of all, I have personally known AFC Cochran for many, many years.
These are his words not mine.
He would have never, ever phrased a statement in that manner incorrectly.
Atlanta Fire Chief Kelvin Cochran disclosed Thursday night that other parts of I-85 had been "compromised" — including the important interchange over Piedmont Road, which leads to the state Capitol.

Depending on the companion chemistry, yes, fire can cause steel to fail. Throw in some magnesium or maybe even some Phosphorous into the mix, or another half a dozen different reactive metals and it can occur.
In the case of the World Trade Center, another item that contributed to the fire getting so hot was the bellows effect (the introduction of additional air into the fire through the windows of the building).
Think of it this way: ancient man could melt iron with their wood-burning/charcoal-burning smelting furnaces because they also introduced additional oxygen to the fire through the use of bellows. This made their fires burn hotter -- hot enough to melt metal.

A well breathing fire isn't the same as a smelting / blast / forging furnace with artificially injected air flow.
