SYSTEMS AND METHODS FOR PROVIDING BASE ISOLATION AGAINST SEISMIC ACTIVITY

Document Type and Number:

WIPO Patent Application WO/2015/088879

Kind Code:

A3

Abstract:

A pedestal base isolation system assembly including a base plate having an anchoring layer and a top plate slidably positioned above the base plate. At least one of the top and base plates includes a textured surface, wherein desired coefficients of static and kinetic friction between the top plate and the base plate prevent relative movement of the two plates with normal operation and yet allow the top plate to move relative to the base plate during a seismic event. In one example, the sliding surface has a coating such as a polyester (e.g., polyester triglycidyl isocyanurate) or a low surface energy coating (e.g., silicone-epoxy coating). In another example, the seismic isolation system further includes a pedestal for supporting an object on the isolation assembly.
