Diffuse flames burn far cooler.
Oxygen-starved diffuse flames are cooler yet.
The fires in the towers were diffuse -- well below 800ºC.
Their dark smoke showed they were oxygen-starved -- particularly in the South Tower.

So much data and facts except you forgot the part about impact and pressure... You think that impact may have some how possibly maybe weakened those beams? Nah.. it's all about temperature.. those beams were pristine after a hit from a jet liner, that makes perfect sense. How about gravity? Wouldn't the weight above the impact effect the beams that were melting? Yes of course it would. But you are talking about melting points in a controlled state aren't you?
you fail at physics and science in general. Learn to work a variable stop learning from youtube and blogs.
