Abstract
Earthquake protective systems offer an alternative technique to conventional
seismic resistant design for improving the seismic performance of civil
structures. These systems reduce the seismic forces by changing the stiffness
andlor damping in the structures. Whereas conventional seismic design is needed
for an additional strength and ductility to resist externally applied earthquake
forces. The research and development works of such systems including passive,
active and hybrid devices are ongoing intensively. The goals of this paper are to
present a brief history of isolation techniques and to introduce these systems
from passive devices to sophisticated ones and completely active systems. By
focusing especially on the passive systems, development and p
