Because of the enormous forces this tower would see - and because of its sheer size - such a passive system would not be possible. Instead, it would require computer monitoring and real-time adjustment through new, "active" stabilization systems. The system itself would be revolutionary, but, as with anything that does not really solely on gravity, has the potential to fail under particular scenarios - some outlined by Chriss. I believe Burj Dubai uses a combination of passive and active systems.

I remember hearing something about this in the Shimizu's Pyramid on "MegaStructures" and "Extreme Engineering".
