Abstract

Salah satu upaya untuk mengurangi kerusakan akibat gempa bumi terhadap struktur adalah dengan mengembangkan desain struktur menggunakan system isolasi dasar pada bangunan (base isolated structure). Pada skripsi ini akan ditinjau system isolasi HDRB dan FPS, mekanisme kerja HDRB adalah menggunakan karet berlempengan baja di dalamnya, kegunaan karet adalah untuk mengurangi getaran gempa sedangkan lempengan baja digunakan untuk menambah kekakuan bantalan karet sehingga defleksi dan deformasi bangunan saat bertumpu di adari pendulum untuk memperpanjang periode alami struktur sehingga dapat terlindungi dari gaya gempa. Analisa ini digunakan untuk mengkaji penggunaan base isolator (HDRB dan FPS) bila dibandingkan dengan bangunan tanpa isolator (fixed base). Dari output SAP2000 penggunaan base isolator dapat memperkecil interstory drift pada bangunan dan memperbesar periode alami struktur, dari Output ANSYS Workbench ternyata struktur yang lebih efektif adalah base isolator (HDRB dan FPS), tetapi lebih mendalam lagi Friction Pendulum System (FPS) memiliki perpindahan (displacement) yang besar karena adanya koefisien friksi. Kata Kunci : Base Isolation, HDRB, FPS, SAP2000, ANSYS Workbench. / One effort to reduce earthquake damage to the structure is to develop the design of structures using base isolation system in the building (base isolated structures). In this thesis will be reviewed system isolation HDRB and FPS, the working mechanism HDRB is using rubber berlempengan steel in it, the usefulness of the rubber is to reduce the tremor while the steel plates used to increase the stiffness of the rubber pads so that the deflection and deformation of the building while resting on rubber pads are not big. Mechanism of action of FPS is to mengguanakan characteristics of the pendulum to extend the natural period so that the structure can be protected from earthquake forces. This analysis is used to assess the use of the base insulator (HDRB and FPS) when compared to buildings without insulator (fixed base). Of output SAP2000 use of base isolators to minimize Interstory drift in buildings and increase the natural period of the structure, from Output ANSYS Workbench turned out to structure the more effective is the base insulator (HDRB and FPS), but are more deeply Friction Pendulum System (FPS) has a displacement (displacement ) is large because of the friction coefficient. Keyword : Base Isolation, HDRB, FPS, SAP2000, ANSYS Workbench.
