Abstract
Indonesia merupakan negara yang berada pada pertemuan tiga lempeng tektonik dunia sehingga memiliki ancaman gempa yang cukup tinggi. Gempa bumi merupakan salah satu beban dinamis yang dapat menimbulkan gaya lateral yang sangat besar pengaruhnya dan sering menjadi faktor utama penyebab deformasi pada struktur baik dalam arah vertikal maupun dalam arah horizontal. Baja merupakan salah satu material yang baik digunakan dalam pembangunan struktur tahan gempa. Hal ini disebabkan sifat dari baja yang daktail. Salah satu sistem pada struktur bangunan baja yang dirancang untuk menahan gempa adalah sistem dinding geser pelat baja. Dinding geser plat baja adalah sebuah sistem penahan beban lateral yang terdiri dari plat baja vertikal padat yang menghubungkan balok dan kolom di sekitarnya yang terpasang sepanjang ketinggian struktur sehingga membentuk sebuah dinding penopang. Dalam tugas akhir ini, Gedung Apartemen Grand Dharmahusada Lagoon dimodifikasi menggunakan struktur baja beton komposit (Concrete Filled Tube) dengan sistem Steel Plate Shear Wall yang memiliki ketinggian 20 lantai dan 1 basement. Perhitungan struktur ini mengacu pada peraturan-peraturan yang berlaku diataranya SNI 1726:2019 tentang Tata Cara Perencanaan Tahan Gempa Untuk Bangunan Gedung dan Non Gedung, SNI 1729:2015 tentang Spesifikasi untuk Bangunan Gedung Baja Struktural, PPIUG 1983 tentang Peraturan Pembebanan Indonesia Untuk Gedung, Steel Plate Shear Wall AISC 20 Steel Design Guide dan SNI 1727:2013 tentang Beban Minimum Untuk Perencanaan Bangunan Gedung dan Struktur Lain. Beban gempa dihitung dengan metode beban gempa dinamis respons spectrum, kemudian dianalisis dengan menggunakan program bantu komputer ETABS.
Dari analisis dan hasil perencanaan diperoleh hasil yaitu : Tebal pelat atap dan lantai 9 cm, dimensi balok induk WF 800x300x14x22, WF 700x300x13x20, dan WF 600x300x12x17, dimensi balok anak WF 500x200x11x9, WF 450x200x9x14, dan WF 400x200x8x13, dimensi kolom basement 1100x1100, dimensi kolom lantai 1-10 CFT 700x700x40x80, dimensi kolom lantai 11-20 CFT 600x600x25x50, dimensi kolom VBE CFT 800x80032x64, dimensi HBE WF 800x300x14x22, tebal SPSW 4 mm. shearwall basement tebal 30 cm. Base plate menggunakan ukuran 1100x1100. Perencanaan pondasi menggunakan tiang pancang precast diameter 50 cm kedalaman 18 m dan diameter 80 cm kedalaman 34 m.

Indonesia is located at the confluence of three active tectonic plates of the world so potentially having a high earthquake threat. Earthquake is one of the dynamic loads that can produces a large lateral force and frequently become a major factor causing structural deformation, both in the vertical and horizontal direction. Steel is one of the proper materials used in the construction of earthquake resistant strucures. This is due to the ductile character of the steel. One of the systems in the steel structure that is designed to withstand an earthquake is the steel plate shearwall system. Steel plate shearwall is a lateral load retaining system which consists of a solid vertical steel plate that joins the beams and columns around which are mounted along the height of the structure to form a supporting wall. In this final project, the Grand Dharmahusada Lagoon Apartment Building was modified by using a concrete steel structure composite (Concrete Filled Tube) with steel plate shearwall system that has a height of twenty floors and one basmenet. Calculation of this structure refers to the applicable regulations including SNI 1726:2019 Earthquake Resistance Planning Standars for Building and Non Building Structure, SNI 1729:2015 Specifications for Structural Steel Building, PPIUG 1983 Indonesian Regulations for buildings, AISC 20 Steel Design Guide and SNI 1727:2013 Minimum Load for the planning of buildings and other structure. Earthquake load is calculated by using the dynamic earthquake spectrum response, then analyzed using program in the ETABS. From the analysis and the results of planning obtained results, namely : thickness of roof plates and floors are 9 cm, the dimensionsof main beam are WF 800x300x14x22, WF 700x300x13x20, and WF 600x300x12x1, the dimensions of secondary beams are WF 500x200x11x9, WF 450x200x9x14, and WF 400x200x8x13, the dimension of basement column is 1100x1100, the dimension of the 1-10 floor columns CFT 700x700x40x80, the dimension of the 11-20 floor columns CFT 600x600x25x50, the dimension of VBE column is CFT 800x80032x64, the dimension of HBE beam is WF 800x300x14x22, 4 mm SPSW thickness. Shearwall basement uses 30 cm thick. Base plate uses a size of 1100x1100. Planning foundation using 50 cm diameter precast pile with 18 depth and using 80 cm diameter precast pile with 34 depth
