Base Isolation Systems in Skyscrapers?

[George3]

I was wondering if base isolation systems are used in the design and construction of skyscrapers. I was reading up on base isolation systems and they seem to be used in normal sized buildings frequently. Anyways, if anyone could give me some examples of base isolation systems being used in skyscrapers it would be much appreciated.

Do some searches for the big sky scrapers in Asia. I am always seeing shows on Discovery Channel on how they are built and the very cool methods they use for earthquake proofing.
