The question is: how does the number for a steel structure compare to that of a steel one?

  This doesn't answer the question, but on topic: I was working with a building engineer who described a situation where a car engine caught on fire underneath a buildings (large, extended) eve that was built with steel beams, and they did melt, obviously necessitating a lot of fix-up work. He reckoned though that if the beam was built of wood, in that situation you'd just have to clean of some blackened material and carry on business-as-usual. He also said that of steel, perfect glass, and wood, glass was (strength to weight) the strongest material (I don't remember if this was in compression, or tension, or ...), but it's so affected by its environment (chemically, physically (a scratch)), there's really no such thing as perfect glass, so it's moot.
