Abstract

Functional Bearing Model (FBM) adalah konsep penginterpretasian rubber bearing sistem yang biasanya diasumsikan sebagai satu link yang terdiri dari beberapa parameter penyusun device tersebut menjadi 3 link berdasarkan fungsi masing-masing parameter. Tiga link tersebut merupakan representasi dari Friction Element pada interface bagian atas, Rubber Element, dan Friction Element pada interface bagian bawah. Penelitian mengenai prototip jembatan yang telah diskala menyesuaikan dengan ukuran shaking table test dibebani dengan seismic loading test dari Chi-Chi Earthquakes yang telah direkam pada stasiun gempa TCU068, TCU102, dan TCU052. Dengan konsep FBM dapat terbukti bahwa setiap komponen penyusun dari rubber bearing system dapat diketahui secara terpisah. Tujuan dari penelitian ini yaitu: untuk mengetahui pengaruh dari variasi koefisien friksi yang diaplikasikan pada interface atas dan bawah rubber bearing system, untuk mengetahui parmeter-parameter apa saja untuk mendesain rubber bearing yang tepat untuk tipe jembatan dengan gempa tertentu, untuk mengetahui berapa jarak gap yang perlu disediakan untuk menghindari tubrukan antar deck pada saat gempa terjadi, dan terakhir untuk mengetahui ukuran dudukan jembatan yang perlu disediakan untuk menghindari slip pada jembatan pada saat gempa terjadi.

English Abstract

Functional Bearing Model (FBM) is an idea to represent 1 link analysis that used in common with divide it into 3 links based on each function. In this research, the rubber bearing divided into 3 elements as representation of rubber bearing system, they are: Friction element in the top of sliding interface between bearing and deck, Rubber in the middle link as a restoring element, and Frictional element in the bottom of sliding interface between bearing and column. A shaking table size bridge proposed under the normalized peak ground acceleration under the design spectra of the near fault ground motions of Chi-Chi earthquakes TCU068, TCU102, and TCU052. In this research of FBM analysis, proof that the contribution of the rubber element and friction elements can be calculated independently. The purposes of this research are: First, to study about the effect of variation of the friction coefficient that applied on the top surface and bottom surface of the rubber bearing system. Second, to study about determining several configuration of the friction coefficient to design a proper rubber bearing system. Third, to study about determining several configuration of the friction coefficient to design a gap between two decks in order to avoid the decks crashing when the earthquakes happen. Fourth, to study about determining several configuration of the friction coefficient to design enlargement of the column’s cap beam in order to avoid the decks falling when the earthquakes happen.
