if building A was a 2 story with the second floor being held up by a steel beam that was 12"x12"x16' and building B was also a 2 story with the second floor being held up by a wooden beam that was 12"x 12"x 16' and both buildings caught on fire at the same time and burnt for a period of time to where the temperature of both buildings reached 2,000 degrees, I wonder which building would collaps first?

steel. it would loose most of its strength at that temp. the wood beam would burn on the outside, but stay solid on the inside and be able to hold the weight

Hi,
Presuming the wooden beam has been treated suitably then it would stand longer. The wood would retain a large percentage of it's strength while it burnt through and the charring produced on its outer surface would afford it a degree of protection form further degradation The steel beam, however, would fail at about 1600 degrees and could in any case buckle causing collapse of structures it supported.

I AM THINKING STEEL IS SUPPOSE TO BE THE BEST ON HOLDEN UP HEAVY WEIGH...BUT IF FIRE GETS UP TO 2000 DEGREES THAT IS VERY VERY VERY HOT HEAT...AND I LEARN ALONG TIME AGO THAT WHEN STEEL GET HOT LIKE THIS...IT WHATS TO BEND...AND THE WOOD BEAMS,I THINK THE WOOD WOULD STILL HAVE ENOUGH LEFT TO BEABLE TO SUPPORT THE FLOOR...SO IT WOULD HAVE TO BE BUILDING A...

Its been done, the steel building collapses first, actually it bends down from the bending steel. Wooden structures of that size have been proven to outlast those temps.

Most likely the one with wood. Buildings that were built with steel have special like wrapping on it that is fire proof. If you ever watch a Sept. 11th special, they show you it.

the wood. cause steel melt before burning and wood don't melt, but only burn, so the building with the wooden beam would collapse first.

I once worked with a civil engineer that did a study of this and he concluded that the wood would hold up longer as many here have stated.

NOT SURE WHY I'M ANSWERING THIS QUESTION I HAVE NO IDEA BUT I GUESS THE STEEL BEAM 2 STORY WOULD FALL FIRST LESS TO BURN...FASTER TO COLLAPS ...STEEL WOULD ALSO GENERATE HEAT TO BURN FASTER...

Not enough info.But I would go with the steel also because of the temp and exposure.

building A and B will collapse first before building C....brick.
