In a high risk building like hospitals, laboratories, or school, the response of the building due to earthquake might be very dangerous. To reduce victims and damages in infrastructure, a type of base isolation is installed to the foundation of the building. The base isolation, in form of a laminated rubber bearing, produces a horizontal movement of the structure when subjected to earthquake forces in order to keep the people and equipment safe. Some calculations of the response vibration parameters are observed to determine the optimal characteristics of the base isolation. The Keq Value is 415,120,000 N/m and the total mass of the building is 739,534,249.7 kg as well as the highest vibration force is 4,015,079,348.47 N. The aim of this research is to simulate the lateral motion of the building with base isolation, due to earthquake forces and decide whether the response is as expected of the design.
