Abstract: Seismic base closing off is widely victimized as a method acting for limiting the damage caused to buildings, bridges, and other structures during a seismic case. Currently, one of the most favourite methods of achieving seismic base closing off is to cut-in elastomeric bearings atomic number 85 the foundation of a structure.Author: Matthew Scott FlorianPublish Year: 2012

How is base isolation used in structural control?
Among the structural control schemes developed, seismic base isolation is one of the most promising alternatives. It can be adopted for new structures as well as the retrofit of existing buildings and bridges. the predominant frequency contents of the earthquakes, as indicated by Fig. 1.
What are the fundamentals of seismic base isolation?
Wher eas floors, which further mitigates the overturning moment of the structure. bearing (LRB) and the high-damping rubber bearing (HDRB). The sliding-ty pe bearings, on the other hand, are impractical due to lack of restoring capability. To overcome this drawback, between the sliding interfaces helps in dissipating energy.
Why are friction pendulum bearings used in seismic base isolation?
The friction pendulum bearings provide strength and stability that exceed those of rubber bearings. Its properties are not affected by aging or temperature. The bearing’s low profile, high strength, and high vertical stiffness reduce installation costs. buildings, bridges and industrial facilities.
