I'm aware of the central supports around the service core, to which the floor trusses from the outer skin were joined. Not your typical boxes of steel beams. The main structure of the building was still it's tubular skin. Perhaps the steel, which also had to be shipped to the original building site, arrived in 30' sections? I saw a great animation of the collapse using a cutaway WTC somewhere, which made a lot of sense to me. One floor collapsed onto another, overloading it, and so on to the ground, with the structural core and skin preventing toppling as it was sucked in at the top.
