I like 9/11 conspiracies as much as the next person, but this one is lame; it's about two totally different kinds of structures: traditional Spanish I-beam & concrete throughout all levels and sections, vs. WTC tubes, with massive beams around the outside and light-weight cross-beam interior flooring.

Making this comparison weakens the arguments about a conspiracy, making conspiracists seem dumb. Instead, stick to the better theories.

The point here is that this Spanish building burned throughout, for many hours. Every structural member was under thermal stress. . .yet it stood. On 9/11, the buildings were on fire from the point of impact - UP. The lower 80 floors were not on fire, and not structurally weakened by the thermal stress of fire - yet the strength of those floors evaporated all at once when the top floor started moving down.
