Abstract
Besarnya beban gempa yang terjadi pada struktur bangunan tergantung dari beberapa faktor yaitu massa dan kekakuan struktur, waktu getar alami dan pengaruh redaman dari struktur, kondisi tanah, dan wilayah kegempaan dimana struktur bangunan tersebut didirikan. Massa bangunan merupakan faktor yang sangat penting, karena beban gempa merupakan gaya inersia yang besarnya sangat tergantung dari besarnya massa dari struktur.
Terdapat banyak alternatif-alternatif penggunaan baja yang lebih baik seperti penggunaan cold formed steel (baja canai dingin). Dibandingkan dengan hot rolled steel (baja canai panas), cold formed steel memiliki beberapa kelebihan. Dengan memiliki sifat yang lebih ringan dan mudah dalam pemasangan cold formed steel juga bisa diproduksi sesuai dengan bentuk dan dimensi yang dinginkan. Karena cold formed steel memiliki sifat yang relatif ringan dibandingkan hot rolled steel maka dalam penggunaaanya bisa lebih efesien pada struktur gaya dalamnya yang tidak terlalu besar dan dapat mengasilkan desain yang lebih hemat.
Pada perhitungan struktur gedung dengan sistem Cold Formed Steel ini mengacu pada Standar Perencanaan Ketahanan Gempa Untuk Struktur Bangunan Gedung SNI 03-1726-2012, Tata Cara Perencanaan Struktur Baja Canai Dingin SNI 7971-2013,Tata Cara Perencanaan Struktur Baja Untuk Struktur Bangunan Gedung SNI 03-1729-2015, dan Peraturan Pembebanan Indonesia Untuk Bangunan Gedung PPIUG 1983. Dengan menganalisis strukturnya ditinjau dengan pengaruh beban gempa dinamik dengan menggunakan program bantu Etabs.
Dari analisa dan hasil perhitungan diperoleh hasil, yaitu tebal pelat bondeks 9 cm, dimensi balok induk WF400x200x8x13, dimensi cannal cold formed 300x65x8,dimensi siku cold formed 40x40x8, dimensi bresing box 100x100x6x6, dimensi kolom lantai 1-4 kingcross 700x300x13x24, lantai 5-8 box 300x300x16. Perencanaan pondasi menggunakan tiang pancang spun pile 50 cm dan 40 cm dengan kedalaman 20,5 m.

The magnitude of seismic load that occurred in the structure of the building depends on several factors: the mass and stiffness of the structure, a natural frequency built and damping effect of the structure, soil conditions, and the seismicity of the area where the building structure is erected. Mass of the building is a very important factor, because the seismic load inertia magnitude depends on the size of the mass of the structure. There are many alternatives that better use of steel as the use of cold formed steel (cold rolled steel). Compared with hot rolled steel, cold formed steel has several advantages. By having properties that are lighter and easier to install cold formed steel can also be manufactured in accordance with the desired shape and dimensions. Because of the nature of cold formed steel has a relatively light compared to hot rolled steel then in the use of it is more efficient on the inside structure that is not too large and can result more efficient design. In the calculation of building structures with Cold Formed Steel system refers to the Earthquake Resilience Planning Standards For Building Structures SNI 03-1726-2012, Planning Procedures for Cold Rolled Steel Structures SNI 7971-2013, Planning Procedures for Structural Steel Building Structures To SNI 03 -1729-2015, and Indonesian Loading Regulation for Building PPIUG 1983. By analyzing the structure is reviewed by the effect of dynamic seismic load by using ETABS auxiliary program. From analysis and the calculation results, namely bondex plate thickness is 9 cm, beam dimension is WF400x200x8x13, cannal cold formed dimension 300x65x8, angle cold formed dimension is 40x40x8, bresing box dimension is 100x100x6x6, kingcross floor 1-4 dimension is 700x300x13x24, floors 5-8 box 300x300x16. Pile foundation design is using spun pile of 50 cm and 40 cm with a depth of 20.5 m.
