Base isolation for the buildings

Base isolation system is introduced in high rise buildings is to prevent the damage due to seismic forces. In base isolation system suspension or series of bearing pads is introduced in-between sub-structure and superstructure. When the earth shakes due to seismic forces, the suspension prevents the force transfer from ground to the superstructure. The isolators are designed in a way to absorb energy and induce a damping effect on the building. The buildings don’t experience the movement due to earthquake because of the flexibility of structure acquired by base isolation.
