This is probably futile, but: You really don't know what failures occurred or how the towers were built, do you?
You need - repeat,
NEED - to read the following threads before continuing on with your arguments:
Two of those were started by another truther making the exact same claim you are, so you should find the opening posts to be familiar. The point is that you need to learn how the towers were constructed
and how the failures occurred on that day before making any further claims.
And I just showed you that that's
not what Eagar said. Did you even read the article I linked in which he discussed temperatures?
NCSTAR 1-5 and all the subreports. It's all there.
NCSTAR 1-3C. It's all there too. You really should read the material before claiming it isn't present.
Or, the forces of the rubble landing on itself in the pile might have had something to do with it. You realize, of course, that nobody on the FEMA site teams managed to recover any steel before it hit the ground and had the rest of the rubble subsequently land on it, do you?

Here's the problem: You're starting to run squarely afoul
Logan's Law. You also do not have the knowledge about the recovered steel inventory, the failure modes, or the experiments that many people here do; your questions demonstrate this. You need - I say again,
NEED - to research what happened before you continue any further. If you do not understand that the columns lost lateral support when the floors failed, and how the falling rubble could fail the floors at the connection points to the columns, then you will not understand why so many columns were indeed not buckled in the middle but instead showed signs of failure at their connection points to each other. If you do not understand that the critical detail to master is the floor truss to column connections, then you do not understand the collapse. It's that simple.
Read those linked threads. It'll help you understand things. Honestly.
