VERTICAL SEISMIC ISOLATION OF ANCIENT STATUES DISPLAYED IN BASE ISOLATED MUSEUM BUILDINGS
Abstract
In order to protect the precious art and historical objects on display, recently the museum buildings in earthquake prone countries are designed and constructed with seismic base isolation devices, at the foundation level. However, when adopting conventional base isolation devices (e.g. LRB, friction pendulum), the horizontal accelerations in the building can be significantly reduced, while the vertical accelerations are directly transmitted to the building’s contents. If these vertical accelerations reach significant values, the stability of the objects decreases against overturning, and this causes the object to lose its full contact with the ground and to start rocking. Therefore, to protect the contents of a base isolated museum building against three dimensional earthquake excitations, a vertical seismic isolation solution must also be introduced at the base level of the object. This study aims to assess the performance of vertical isolation devices for the seismic protection of the ancient statues displayed in base isolated museums.
