Abstract
We propose the use of robust control in conjunction with base isolation in order to assure arbitrarily small motion of a seismically excited structure. The proposed method requires control force application only at the base (first) floor. The efficacy of the scheme is illustrated by extensive simulations for a prototype six-story building.
