Abstract
Perencanaan gedung tinggi harus mengikuti persyaratan gempa mengingat Indonesia berada di kawasan dengan kemungkinan terjadinya bencana gempa yang cukup tinggi. Salah satu sistem pada struktur bangunan baja yang dirancang untuk menahan gempa adalah sistem Eccentrically Braced Frame (EBF). Sistem ini memiliki kekakuan yang sangat baik mirip dengan sistem Concentrically Braced Frame (CBF) dan daktilitas yang baik mirip dengan sistem Momen Resisting Frame (MRF). Konsep EBF adalah adanya elemen link yang akan mengalami kerusakan apabila terjadi gempa, namun elemen lain tetap berada dalam kondisi elastik. Dalam tugas akhir ini, Isabella Tower Grand Kamala Lagoon Bekasi dimodifikasi dari gedung berstruktur beton bertulang menjadi struktur baja dengan sistem EBF yang memiliki ketinggian 22 Lantai. Konfigurasi EBF menggunakan konfigurasi V-Braced. Pada perencanaan ini mengikuti persyaratan keamanan struktur berdasarkan SNI 1729-2015, SNI 03-1729-2002, SNI 1726-2012, SNI 2847-2013, dan SNI 1727-2013 Dari hasil analisa yang telah dilakukan, diperoleh hasil yaitu: pelat lantai dan pelat atap menggunakan bondek tebal 9 cm, dimensi balok induk menggunakan WF 600x200x11x17, panjang elemen link 80 cm, dimensi bresing WF 300x300x10x15, dimensi kolom CFT 700x700x28. Perencanaan pondasi menggunakan tiang pancang beton diameter 60cm dengan kedalaman 18 meter dan dimensi sloof 40x60 cm

High-rise building planning in Indonesia should meet the requirements of structural seismic design because Indonesia is located in high probability earthquake occur. One of the steel structure system that used for seismic design is Eccentrically Braced Frame (EBF). This system provides high levels of both elastic stiffness similar to Concentrically Braced Frame (CBF) and ductility similar to Moment Resisting Frame (MRF). EBF design concept is the link designed to be the element that will broke while the other elements remain in elastic condition. In this final project, Isabella Tower Grand Kamala Lagoon Bekasi is modified from reinforcement concrete system into steel structure using EBF system that has 22 stories, and using V-Braced configuration. In this planning will meet the requirement of structural safety based on SNI 1729-2015, SNI 03-1729-202, SNI 1726-2012, SNI 2847-2013, SNI 1727-2013 The results of the analysis and calculation is: the thickness of the floor and roof deck are 9 cm, the dimension of primary beams is WF 600x200x11x17, the length of link elements are 80cm, the dimension of bracing is WF 300x300x10x15, the dimension of column is CFT 700x700x28. For foundation using 60cm diameters of concrete piles with 18 meters depth, and the sloof dimension is 40x60 cm
