Constructed by the Port Authority of New York and New Jersey in the early 1970s, the World Trade Center towers were, for their time, the best known examples of tube buildings. Tube buildings are strengthened by closely spaced columns and beams in the outer walls. The closely spaced columns and beams in each tower form a steel tube that, together with an internal core, withstand the tremendous wind loads that affect buildings this tall.
Aside from withstanding enormous wind loads, the World Trade Center towers were also constructed to withstand settlement loads. Because the towers were built on six acres of landfill, the foundation of each tower had to extend more than 70 feet below ground level to rest on solid bedrock.

Since they collasped as easily as they did on 9-11, I doubt there was an inner core.

No. It was a thin exo skeleton. Both Popular Mechanics and Popular Science had a good issue recently on why they collapsed so easily.

No. a solid core would not allow the buildings to sway in the wind.
