There are multi axis versions of op's vidya. This version is expensive, hard to scale up to building size.
The ones I see on most new skyscrapers are tendon based, that is an actuator is connected to a tendon-cable that runs in sets down the sides of a tower into the foundation. They are differentialy tensioned (spelling) as the wind/ground moves. Shorter (<5-6 floors) buildings go for the "out-muscle it" approach, using k-rails, shear diaphragms (horizontal plane) and shear panels/walls (vertical plane) to resist earthquakes/high wind loading. these are usualy engineered up to a 9.0 quake (I might be off on the magnitude).
Source: I work in commercial/industrial construction, and used to work in residential construction.
There have been building designs with counter balance water tanks and segmented stories and shock absorbers and other techniques... I don't know how often such things were actually deployed however.
