Second, the values of vertical and horizontal stiffness and damping values were analysed in a case study of a ten-stories hospital building located in Padang, West Sumatra, Indonesia using nonlinear time history analysis of seven different ground motion values. First, elastomeric base isolators were modelled in the finite element software to obtain vertical and horizontal stiffness and damping values based on local rubber of mechanical properties that is obtained from the previous tests. In this study, a numerical two-stage analysis was carried out to evaluate the behaviour of elastomeric base isolators. Therefore, earthquake dissipated devices such as elastomeric base isolator is needed to minimize building’s damages when an earthquake occurs. Indonesia is located in high seismic zones.
