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.

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.

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.
