Abstract

Indonesia merupakan daerah yang rawan sekali terkena bencana gempa yang dimana dapat merusak bangunan di sekitar pusat gempa, terutama bangunan yang menggunakan beton pada struktur utamanya. Baja merupakan alternatif bangunan tahan gempa yang sangat baik. Jika dibandingkan dengan struktur beton, baja dinilai memiliki sifat daktilitas yang dapat dimanfaatkan pada saat struktur memikul beban akibat gempa. Salah satu alternatif dalam merancang bangunan gedung baja tahan gempa adalah dengan menggunakan Sistem Rangka Bresing Eksentrik. Sistem Rangka Bresing Eksentrik (SRBE) adalah suatu sistem rangka bangunan baja yang menggunakan bracing sebagai pengaku dan elemen link yang mampu mendisipasi energi gempa melalui mekanisme plastifikasi. Kelebihan sistem ini adalah daktilitas struktur yang baik dengan mekanisme kelelehan geser yang terjadi pada link pendek. Link adalah bagian pada elemen struktur balok yang dibentuk oleh perpotongan balok dan bresing. Pada perhitungan struktur gedung dengan sistem SRBE ini mengacu pada Standar Perencanaan Ketahanan Gempa Untuk Struktur Bangunan Gedung SNI 03-1726-2012, Tata Cara Perencanaan Struktur Baja Untuk Struktur Bangunan Gedung SNI 03-1729-2015, dan Peraturan Pembebanan Indonesia Untuk Bangunan Gedung PPIUG 1983. Dan dalam menganalisis strukturnya ditinjau dengan pengaruh beban gempa dinamik dengan menggunakan program bantu SAP 2000. ii Dari analisa dan hasil perhitungan diperoleh hasil, yaitu tebal pelat bondeks 9 cm, dimensi balok induk WF350x250x9x14, balok link WF500x200x10x16, dimensi bresing WF 300x300x15x15, dimensi kolom lantai 1-4 komposit CFT 700x700x22, lantai 5-8 komposit CFT 600x600x22, lantai 9-12 komposit CFT 500x500x22, lantai 13-16 komposit CFT 400x400x22, dan panjang elemen link direncanakan 100 cm. Perencanaan pondasi menggunakan tiang pancang spun pile 50 cm dengan kedalaman 30 m. Sloof ukuran 40 cm x 60 cm dengan tulangan utama 4D22 dan tulangan geser Ø12-200. ======================================================================= Indonesia, due to its high frequency of earthquake, is famous for its land’s fragility on most of its area. The potential damage the natural disaster can bring to the buildings within its reach is considerably high, especially for those which are mostly concrete-structured. As science expands human’s horizon, it is now believed that Steel is one of good alternatives to become the foundation of an earthquake-resistance building. Compared to the one that is concrete, steel has ductility character which can be used to hold load from the potential effects of the earthquake. One of the alternatives in planning a steel construction building which is earthquake-resistance is Eccentrically Braced Frame. Eccentrically Braced Frame (EBF) is a steel construction building which use bracing as stiffer and link element which can dissipate the earthquake power through plasticity mechanism. The advantage of this system is a good ductility structure with shear melting mechanism which works in the short link. Link itself is a part in bar structure element made from the cutting between bar and braced. 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. iv From the analysis and calculation result, it was found that the thickness of bondex plat was 9 cm, the bar dimension was WF 350x250x9x14, the link bar was WF 500x200xx10x16, the braced dimension was WF 300x300x15x15, the first to forth composite floors column dimension were CFT 700x700x22, the fifth to eighth composite floors were CFT 600x600x22, the ninth to twelfth composite floors were CFT 500x500x22, the thirteenth to sixteenth composite floors were CFT 400x400x22, and the length of link element was planned 100 cm. The planning of foundation used 50 cm spun pile pole with 30 m of depth. It also used 40 cm x 60 cm sloof with 4D22 as the main reinforcement and Ø12-200 as the shear reinforcement.
