The modeling of pot bearings in the ETABS program is modeled as a link property element.

Type of support on the sky-bridge in the parkirng building is multidirectional pot bearing and in the main building is fixed pot bearing. The sky-bridge connects the two buildings, parking building (8 floors) and the main building (21 floors). In this study an evaluation of the structure of the sky-bridge at Tarumanagara University campus 1 on earthquake regulations SNI 1726 : 2019. Therefore, the use of local rubber for elastomeric base isolators is promising a good future for the advancement of the construction industry in Indonesia. The studied results showed that the structure with base isolators using a local rubber base material can reduce damage caused by the earthquake with an indication of an increase in time period, decreased base shear, and also a decrease in displacement of the structure. 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.
