Basically you have 35,000 pounds of JP4 jet fuel. Steel beams melt between X and X. This info is unpublished for a reason. The biggest random at this point is how well those beams are protected by fireproofing. Additionally, the outer skin of the building (which is the strongest part of the building) was attached by metal tabs and it was these tabs that failed in the fire. Then physics takes over. Concrete weighs about 150 pounds a cubic foot (with rebar). You are staring at a building collapse. The building was designed to take a strike from a Boeing 707 and survive. The airliner that stuck the towers had a much bigger fuel load.

Also, steel doesn't have to melt to fail. It weakens rapidly with increases in temperature, hence the need for fireproofing on structural members,
The same fireproofing likely to have been partially stripped away by a freaking airplane crashing into it.
