Seismic Vibration Control of Building with Lead Rubber Bearing Isolator

Kalpa Publications in Civil Engineering, 2018
During the life span of structure there may be an effect of vibration. Due to vibration there may be major or minor damage in building. Base isolation is best method to reduce the seismic response of the structure. This paper gives idea about base isolation system which can be used in multi-story building to reduce seismic response of the structure ...

Modeling the Response of a Lead Core Rubber Bearing for Seismic Isolation

, 2023
Lead core rubber bearings are among the commonly used devices for seismic isolation of buildings and structures. They are a part of the so-called base isolation meant to decouple the superstructure from the ground, thus modifying the structure’s fundamental period and mitigating damage to structural and non-structural elements.
