``Smart'' Base Isolation Systems
This paper investigates the effectiveness of several base isolation strategies for historical earthquakes of various magnitudes and characteristics. The strategies studied herein include isolation systems with lead-rubber bearings and with "smart" (semi-active) dampers. To demonstrate the advantages and disadvantages of the various approaches, historical earthquakes scaled to different magnitudes are used to excite an isolated building structure. Responses examined include: peak base and structural (relative) displacements, peak base and structural (absolute) accelerations, and peak applied forces. The adaptable nature of the smart damper system is shown to protect a structure from extreme earthquakes, without sacrificing performance during the more frequent, moderate seismic events.
