title = "Behavior of rubber base isolator with various shape factors",
abstract = "The base isolator is the most effective technique in decreasing earthquake force that transmits to the building. This system is developed for earthquake protection by increasing the frequency of the structure away from the fundamental frequency of seismic excitation and fixed base structure. The layer number of rubber and reinforcement has an important influence to the vertical and horizontal behaviors of base isolation system. The parameters of shape factor denoted S are used to present the number of layers. A series finite element analysis (FEA) was carried out to study the influence of shape factor (S) of base isolation to the vertical and horizontal behaviors. Three dimensional models of base isolations with different shape factor values were created and analyzed by ANSYS. The models were subjected to axial and combination of vertical and horizontal loads to observe their vertical and horizontal behaviors, respectively. The results of the study indicate that the values of shape factor have no significant influence to the horizontal behavior due to constant thickness of overall rubber layers. On the contrary, the opposite conditions were found on their vertical behaviors. From the study, it can be concluded that the increase of shape factor value gave a considerable impact to the vertical strength of base isolation. In other words, it can be said that the increase of shape factor value also increases the vertical stiffness of base isolators.",
