Seismic response characteristics of seismically isolated building with dead zone mechanism connected to oil damper

Abstract

In recent years, there is concern about the occurrence of extreme ground motions that greatly exceed the amplitude levels and durations expected in conventional design level. Therefore, seismically isolated buildings are required to secure the seismic isolation performance for small earthquakes and to suppress the excessive displacement of seismic isolation layer for extreme ground motions. In this paper, we analyze the seismic response of seismically isolated buildings with the dead zone mechanism connected to oil damper to understand the response characteristics.
