Now the question that has bugged me is why didn't the subsequent central steel columns on the lower floors, which weren't damaged give way with out seemingly any resistance, or why didn't they seemingly affect the fall of the structure.
​
The answer is that the floors in the building weren't designed (and no building is) to withstand the dynamic load of the top quarter of the building falling on it. The equation F = ma shows that the force load goes up as acceleration increases (ie the top of the building falling due to gravity ~9.8m/s/s). No other explaination should be needed.

Re: Please offer me an explanation
Sorry, I mixed up my equations, not enough coffee!
​
Kinetic energy K is found by: K = (mv^2)/2.
​
And the towers had a whole lot of kinetic energy once it started falling
