Smart Base Isolation Systems
Published in the October 2002 issue of the Journal of Engineering Mechanics, this research paper proposes a novel method of seismic base isolation. This technique is used to mitigate "the effects of an earthquake by essentially isolating the structure and its contents from potentially dangerous ground motion." The authors compare their method to several established base isolation strategies by simulating each under varying conditions for historical earthquakes. They show that the derived system
