Powerful earthquakes pose the biggest threats to structures. As a way to break this dilemma, vibration-control measures have been developed. One of the seismic design methods is the Base Isolation Method, also known as Seismic Base Isolation. It is a great way to protect structures from the destructive power of earthquakes. The isolators partially reflect and absorb incoming seismic energy before it is transmitted to the superstructure. An Elastomeric Rubber Bearing Isolator was introduced in this study. Films of rubber with substantially lesser horizontal stiffness are inserted between the superstructure and the foundation. This paper presents the effectiveness of Base Isolation using Elastomeric Rubber Bearing on the future buildings within the Don Honorio Ventura State University - Lubao Campus under the National Structural Code of the Philippines 2015. Linear Dynamic Analysis (Response Spectrum Method) and Nonlinear Dynamic Analysis (Time History Analysis) are used for the design method of this study. A comparative analysis has also been performed between the Base-Isolated and Fixed-Base Structure using Modal Analysis and Dynamic Analysis. With the use of STAAD Software, a three-story structure with a base isolation system is designed. The dynamic properties were compared in different parameters such as modal analysis, dynamic response, base shear, and story drift. The results of the base-isolated structure have successfully passed all the tests, while the fixed-base structure failed on a few assessments. The results show that the proposed technique lessens lateral displacements and possible damages due to seismic forces. Thus, the Base Isolation Method has proven to be an effective earthquake-resisting design method.
