melting steel

I'm sure you've all heard the argument about how the steel in the WTC buildings didn't need to melt it just needed to be weakened and that at 1100 degrees steel loses about 50% of it's strength. Does anyone know how long steel would have to be exposed to say, 1100 degrees before the steel itself would reach that temperature? It just seems to me that the jet fuel would have burned up long before the steel could ever get that hot. I've tried to find some information about this but have had no success.

Don't forget that the steel beams at the WTC were all interconnected and steel is very good in conducting heat away, so it would take IMO a very long time. But there was never before and never after 911 a building made of steel beams that collapsed because of fire. So I no longer think this was the reason for the collapse. For example see this for a possible clue:

Watch this movie about thermite:

Now check the steal beam here back in the middle with the diagonal cut and the black residues that look like something molten.

Thanks kindly for the links. I don't doubt that there were thermite explosives planted through out the buildings in order to demolish them quickly. A bit of jet fuel couldn't so much damage.
