Abstract
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 Eksentrik dimana sistem rangka baja ini menggunakan bresing sebagai pengaku dan Link Beam untuk mendispasi beban lateral (gempa) melalui mekanisme plastifikasi. Kelebihan dari Sistem Rangka Bresing Eksentrik (SRBE) adalah daktilitas struktur dan kekakuan elastik yang baik serta mekanisme plastifikasi pada Link Beam dalam menyerap energi ketika struktur menerima beban lateral (gempa). Link Beam sendiri adalah elemen yang berada di bagian ujung pengaku yang berfungsi menggabungkan antar bagian balok, pengaku, dan kolom.
Pada perhitungan struktur gedung dengan SRBE ini mengacu pada Tata Cara Perencanaan Ketahanan Gempa untuk Struktur Bangunan Gedung dan Non Gedung (SNI 1726:2012), Spesifikasi untuk Bangunan Gedung Baja Struktural (SNI 1729:2015), dan Peraturan Pembebanan Indonesia untuk Bangunan Gedung PPIUG 1983. Dalam menganalisa strukturnya ditinjau dengan pengaruh beban gempa dinamis menggunakan program bantu SAP2000.
Dari analisa dan hasil perhitungan diperoleh hasil, yaitu tebal pelat bondeks 12 cm, dimensi balok induk WF 600x300x12x20, balok link WF 700x300x15x28, dimensi bresing WF 400x400x16x24, dimensi kolom lantai dasar-5 komposit CFT 700x700x25, lantai 6-10 komposit CFT 600x600x25, lantai 11-atap 500x500x25 dan panjang elemen link direncanakan 100 cm. Perencanaan pondasi menggunakan tiang pancang 60 cm dengan kedalaman 26 m. Sloof ukuran 65 cm x 80 cm dengan tulangan utama 16D22 dan tulangan geser D12-200.
=============== 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 1726:2012), the Steel Structure Planning for Building Construction (SNI 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 12 cm, the bar dimension WF 600x300x12x20, the link bar WF 700x300xx15x28, the braced dimension WF 400x400x16x24, ground to fifth floors column dimension were CFT 700x700x25, sixth to tenth floors were CFT 600x600x25, eleventh to rooftop were CFT 500x500x25, and the length of link element was planned 100 cm. The design of foundation used 60 cm spun pile pole with 26 m of depth. It also used 65 cm x 80 cm sloof with 16D22 as the main reinforcement and Ø12-200 as the shear reinforcement.
