For the potential application of smart materials to seismic structural cont
rol, this paper reviews seismic control techniques for civil engineering st
ructures, and developments of smart materials for vibration and noise contr
ol. Analytical and finite element methods adopted for the design of distrib
uted sensors/actuators using piezoelectric materials are discussed. Investi
gation of optimum position of sensors/actuators and damping are also outlin
ed.
