It sounds like we have the same concern. A free-standing steel frame does not readily burn while a wooden frame will. This is obvious.
In a complex building things may not be so simple. Assuming that everything around the structure is great fuel, it's possible that a wooden frame won't significantly increase the speed at which the fire spreads and may actually remain structurally sound longer than a steel supporting structure would. In this case, you might have more time to put out the fire before the building collapses.
Of course, the obvious question is: why not reduce the amount of combustible building material so that fires don't spread so quickly and there's simply not enough fuel to heat a steel support structure to the point of failure? My intuition says that an ideal building shouldn't readily burn to the point that it's structure fails. If part of it catches fire, the fire should burn itself out before this point is reached. I am not an engineer though, and my intuition may very well be wrong. Obviously, fires do happen in glass and steel buildings.
We can build steel-framed buildings that will readily burn to the ground. Can we build wood-framed buildings that won't? This is a complex question to which I don't know the answer.
- jellicle 10y agoI sincerely apologize for linking to a 9/11 denial site, but: http://www.serendipity.li/wot/other_fires/other_fires.htm http://www.serendipity.li/wot/other_fires/other_fires.htm We have plenty of steel skyscrapers that have burned for a LONG time and have not collapsed. Huge fires. Towering infernos. This is a good thing, not only for the residents but also for the neighbors of said structures. I simply do not believe that you can build a building with wood supports that is going to withstand the conditions in those photos without collapsing. Wood skyscrapers that burn are going to collapse with considerable collateral damage. This whole debate is an example of not remembering the past and being doomed to repeat it. Corporate greed to save a few bucks during construction will eventually result in preventable tragedies.
