Analysis of vibration response from high damping rubber bearing and lead rubber bearing for using in high rise building foundations subjected to earthquake

Vibration due to earthquakes that occur in a high rise building like hospital building can disrupt the comfort, as well as operation of the hospital, and can cause casualties because usually, the building response to the earthquake is of a cantilever movement. The solution from a mechanical vibration point of view is to change the response of buildings to earthquakes so that hospital buildings are not destroyed by earthquakes by controlling the response of vibrations that produce lateral movement responses. One technology that is used to increase the resilience of buildings that subjected to earthquake, as well as control vibration response is the application of rubber bearing base isolation on the building foundations. High damping and lead rubber bearings base isolation are used on high rise building foundations which are designed to give lateral motion due to the base isolation construction. The results of computer simulation using ANSYS^® software have shown that the rubber bearing base isolation gave vibration response in lateral motion.
