Core buildings are not new. The first one I worked on here in Chicago was in 1984, so maybe the World Trade was made around the same time. They stick the elevators in the core. Floor beams are welded to the core at steel embeds that are poured in as the core rises. Aside from the actual specs, I've built enough of these and scraped off enough insulation to add beams and whatnot that I can think of a bunch of ways a fire like that could weaken bolted or welded connections. If someone really wanted to figure it out they could. Get the prints, add up all the weight above those floors. Once floor beams start cutting loose you've got a shock load situation that would be highly unlikely to have been engineered into the design.
