Seismic Isolation

Course Description

Seismic isolation system will be explained as one of structural response control methods. The Seismic isolation system is most effective to reduce the response and keep safety of a superstructure. Principles of the seismic isolation, merits and demerits of the seismic isolation system, characteristics of isolators and dampers are explained. Also behaviors of buildings with the seismically isolated buildings during earthquake will be discussed.
