Prediction of base Isolation Performance on Reinforced Concrete Building

Vibration problems can occur in any buildings due to the surrounding activities and becomes more important issues amongst engineers. The vibration can be induced by internal and external sources around the building. The movement of earthquake can be caused of vibration in the building. The vibration will affect the electronic equipment such as computers and may cause the residents to feel uncomfortable in the building. The objective of this paper is to investigate the performance of base isolator at reinforced concrete building due to low amplitude vibration by using finite element ANSYS software. The prediction on vibration response at structural floor based on performance with base isolator and without base isolator. The presence of base isolator is expected to produce more stable and safe building from any vibration either from internal or external excitation. It will increase the stiffness of the structure and thereby reduces its natural frequency. The building will respond to the seismic activity in a rigid manner rather than resonating with its frequency. In terms of sustainability aspects, it will avoid the damaged buildings from the crack etc. and provide more comfort to the occupants inside the building.
