Abstract
Indonesia sebagai salah satu negara dengan daerah rawan gempa, kebutuhan akan bangunan tahan gempa yang mampu memberikan kenyamanan dan keselamatan jiwa di Indonesia tidak dapat dihindari. Salah satu alternatif bangunan tahan gempa yang sangat baik adalah bangunan baja. Bangunan baja memiliki sifat daktilitas yang dapat dimanfaatkan oleh struktur pada saat memikul beban akibat gempa. salah satu sistem yang dapat digunakan adalah Sistem Rangka Bresing Eksentris dimana sistem rangka baja ini menggunakan bresing sebagai pengaku dan Link Beam untuk mendisipasi beban lateral (gempa) melalui mekanisme plastifikasi. Kelebihan dari Sistem Rangka Bresing Eksentris (SRBE) adalah daktilitas struktur dan kekakuan elastik yang baik serta mekanisme plastifikasi pada Link Beam sendiri adalah elemen yang berada di bagian balok, pengaku dan kolom
Pada perhitungan struktur gedung dengan SRBE ini mengacu pada Standar Perencanaan Ketahanan Gempa Untuk Standar Bangunan Gedung SNI 03-1727-2012, Tata cara Perencanaan Struktur Baja Untuk Standar Bangunan Gedung SNI 03-1729-2015, dan Peraturan Pembebanan Indonesia Untuk Bangunan Gedung PPIUG 1983. Dalam menganalisa strukturnya ditinjau dengan pengaruh beban gempa dinamis menggunakan program bantu SAP 2000.
Dari analisa dan hasil perhitungan diperoleh hasil, yaitu tebal pelat bondeks 9 cm, dimensi balok induk WF 300x200x9x14, balok link WF400x200x13x 8, dimensi bresing WF 200x200x8x12, dimensi kolom lantai dasar - 2 komposit CFT 500x500x16, lantai 3-5 komposit CFT 400x400x16, lantai 6-Atap komposit CFT 300x300x16 dan panjang elemen link direncanakan 100 cm. Perencanaan pondasi menggunakan tiang pancang bore pile 60 cm dengan kedalaman 14 m. Sloof ukuran 50 cm x 60 cm dengan tulangan utama 8D22 dan tulangan geser Ø12-200. ============ Indonesia as one of the countries with high frequency of earthquake, the need for earthquake resistant buildings that can provide comfort and safety in Indonesia can not be avoided. Steel buildings is one of good alternatives of earthquake-resistant buildings compared to concrete buildings. Steel have ductility character which can be used to carrying the load due to the earthquake. One of the systems that can be used is Eccentrically Braced Frame System which use bracing as stiffener and link element that can dissipate the lateral loads (earthquake) through plasticity mechanism. The advantages of this system is a good ductility structure and elastic stiffness also the plasticity mechanism on Link Beam in absorbing energy when the structure receives lateral loads (earthquakes). Link Beam itself is a part in bar structure that serves to combine between the beam, stiffener and column.
This EBF building construction calculation depends on the Earthquake Resistance Planning Standard for Building Construction SNI 03-1726-2012, the Steel Structure Planning for Building Construction SNI 03-1729-2015, and the Indonesian Imposition Regulation for Building PPIUG 1983. SAP 2000 has been selected to calculate the effect of dynamic earthquake load, specifically used in analysing the structure.
From the analysis and calculation result, it obtained the thickness of bondex plat was 9 cm, the bar dimension WF 300x200x9x14, the link bar WF 400x200x8x13, the braced dimension WF 200x200x8x12, ground to second floors column dimension were CFT 500x500x16, third to fifth floors were CFT 400x400x16, sixth to rooftop were CFT 300x300x16, and the length of link element was planned 100 cm. The design of foundation used 60 cm bore pile with 14 m of depth. It also used 50 cm x 60 cm sloof with 8D22 as the main reinforcement and Ø12-200 as the shear reinforcement.
