Abstract

Pertumbuhan populasi tahunan di suatu wilayah mengharuskan pembangunan fasilitas perumahan perumahan. Namun demikian, jumlah lahan yang tersedia berbanding terbalik dengan jumlah penduduk, sehingga pembangunan apartemen menjadi solusi untuk mengatasi permasalahan tersebut. Apartemen merupakan tempat yang ideal untuk tinggal di daerah dengan lahan terbatas. Bagaimanapun, jenis bangunannya adalah struktur bertingkat tinggi. Apartemen harus fungsional dan tahan gempa. Salah satu solusi dari permasalahan di atas adalah dengan merancang struktur komposit baja-beton dengan sistem BRBF (Buckling-Restrained Braced Frames). Struktur komposit adalah struktur yang menggabungkan dua atau lebih material dengan sifat berbeda untuk membentuk struktur terpadu dengan sifat gabungan yang ditingkatkan. Sebuah sistem Buckling-Restrained Braced Frame juga direncanakan untuk menahan gempa. Buckling- Restrained Braced Frames (BRBF) adalah sistem rangka baja dengan profil anti tekuk. Profil ini memiliki elastisitas, keuletan, dan penyerapan energi yang luar biasa. Pada tugas akhir ini, Gedung Apartemen Nayumi Sam Tower yang semula dibangun dengan struktur beton bertulang dan dinding geser setinggi 22 lantai, akan dimodifikasi dengan mengurangi jumlah lantai menjadi 15 lantai dengan menggunakan struktur komposit dan sistem BRBF. Kajian literatur proposal ini mengacu pada SNI 1727:2020, SNI 1726:2019, SNI 1729:2020, AISC 341-16, ACI 318-19, struktur gabungan, dan buku teks dan jurnal terkait sistem BRBF. Setelah penulis melakukan perencanaan, pemodelan, perhitungan, serta analisis model objek struktur yang akan dimodifikasi, dan perbedaan mengenai model, penulis menggunakan Tabung Isi Beton dengan berbagai tipe yang CFT 600 x 600 x 25, CFT 500 x 500 x 25, dan CFT 450 x 450 x 25 sebagai Kolom Komposit, serta Balok Sekunder Komposit 400 X 200 X 8 X 13, serta WF 500 X 300 X 11 X 18 sebagai Balok Utama, penulis juga merencanakan Elemen Tahan Gempa yaitu Buckling Restraints Brace Frame, dan berdasarkan material tersebut serta skema pembebanan yang diatur oleh SNI 1729 : 2019, SNI 1726 : 2019, SNI 1727 2019, serta ACI 318 telah memenuhi persyaratan dan modifikasi berhasil dilakukan dengan beban yang diserap oleh sistem bresing mencapai 70% yang berarti hasil yang diperoleh telah memenuhi tujuan pemodelan yaitu untuk mengurangi beban yang bekerja pada struktur primer dan sekunder.

Annual population growth in a region necessitates the construction of residential housing facilities. Nevertheless, the amount of land available is inversely related to the number of people, so building apartments become a solution to solve these problems. Apartments are ideal places to live in areas with limited land. In any case, the type of building is a high-rise structure. Apartments must be functional and earthquake resistant. One solution to the above issues is to design a steel-concrete composite structure with a BRBF (Buckling- Restrained Braced Frames) system. A composite structure is a structure that combines two or more materials with different properties to form a unified structure with enhanced combined properties. A system of Buckling-Restrained Braced Frames is also planned to withstand the earthquake. Buckling- Restrained Braced Frames (BRBF) is a steel frame system with an anti-buckling profile. This profile possesses exceptional elasticity, ductility, and energy absorption. In this final project, the Nayumi Sam Tower Apartment Building, originally constructed with a reinforced concrete structure and shear walls as high as 22 floors, will be modified by reducing the floor count to 15 floors using a composite structure and the BRBF system. This proposal's literature review refers to SNI 1727:2020, SNI 1726:2019, SNI 1729:2020, AISC 341-16, ACI 318-19, composite structures, and BRBF systems-related textbooks and journals. Right after the author did the planning, modelling, calculating , and also analyzing the model that the structure object that will be modified, the author use a analysis, and discrepancy regarding to the model, the author use Concrete Filled Tube with various type which are CFT 600 x 600 x 25, CFT 500 x 500 x 25, and CFT 450 x 450 x 25 as the Composite Column, and also 400 X 200 X 8 X 13 Composite Secondary Beam, and also WF 500 X 300 X 11 X 18 as the Primary Beam, the author also plan an Earthquake Resistant Element which is Buckling Restraints Brace Frame, and based on that material and also loading scheme which controlled by SNI 1729 : 2019, SNI 1726 : 2019, SNI 1727 2019, and also ACI 318 has met the requirement and the modification has successfully made with the load that absorbed by the bracing system up to 70% which means that the the result has fulfilled the modelling purpose which is to reduce the load acting on the primary and secondary structures.
