Mass timber structural members actually perform quite well under fire conditions. It takes quite a lot to burn through a big lump of solid wood.

  Though like we witnessed with the twin towers, all you have to do is weaken them.

    Right, but wood is also a great insulator compared to steel, so where a steel beam's yield strength would go down quickly throughout, you're only going to burn the outer layer of the beam, allowing it to retain most of its strength. /Hand-wavey-assertion

    Wood doesn't quickly weaken during a fire. You slowly lose material as it burns, but the char actually protects the remaining wood. Obviously it will eventually burn, but it's not as fast a process as you might imagine.

    Wood doesn't melt

  i think the problem is that wood self-propagates fire.
