Abstract: Seismic base isolation is one of the commonly implemented and accepted earthquake protection systems. Seismic base isolation is a technique that mitigates the effects of an earthquake by essentially isolating the structure and its contents from potentially severe ground motion, especially in the frequency range where the building is most affected. Being the most critical part of the base isolated buildings, accurate evaluation of structural properties and precise modeling of isolation devices is of utmost importance in predicting the response of the buildings during the earthquakes. The isolation system can be modeled as a linear or nonlinear element. The linear model of an isolation system consists of effective stiffness and effective damping at the design displacement. However, except in preliminary designs, the isolation system is generally modeled as bilinear or nonlinear. This paper is concerned with non-iterative analytical modeling of base isolation system idealized as bilinear system. © 2015 Taylor & Francis Group, London.
