Analisis Respons Struktur Beton Bertulang Tahan Gempa Dengan Base Isolation High Damping Rubber Bearing

---

Indonesia is located on earthquake-prone area and many building structures experience damaged and even collapse. To avoid damage on the building structures during the earthquakes several efforts have been suggested, one of the methods is the application of base isolation. The basic idea of this base isolation system is to isolate the propagation of vibrations caused by the earthquake from the ground to the building structure.
A way to isolate the propagation of earthquake loads is to use a rubber insulator that is installed between the substructure and the upper structure of the building. The instalation of rubber insulators is to extend the structure period to minimize the base shear forces that occur in the structure.
The purpose of this study was to analyze the effect of the use of high damping rubber bearing system to the response of reinforced concrete building structure. In this study the 15-storey hotel building structure with the height of 62.9 m was modelled using finite element (FE) software ETABS v2016. Two three-dimension FE models were constructed, the building without base isolator and with base isolator.The elements of reinforced concrete structure were modelled with frame element while the base isolator was modelled with springs element availbale in ETABS. Static pushover analysis was conducted on the models to obtain fundamental building period and base shear force and to determine performance category of the analyzed structures.
The results of the analysis showed that the fundamental building period and the base shear force of the building without base isolator was 4.212 seconds and 1470.725 tons, respectively, while the fundamental building period and the base shear force of the building with base isolator was 5.500 seconds and 1286.071 tons. It can be concluded that the fundamental period iof the structure with base isolator was increased by about 30.58%, and the base shear force was decreased by about 12.56% compared to those of the structure without base isolator. Furthermore, pushover analysis also showed that the structure with base isolator was better than the structure without base isolator. The structure without base isolator categorized as life safety,which means there is damage to structural components, the stiffness is reduced, but still has an adequate threshold for collapse,than the structure with base isolator categorized as immediate occupancy, which means there was no significant damage existed in the structure, where the strength and stiffness are roughly the same as the conditions before the earthquake
