Abstract
Indonesia adalah negara kepulauan yang terletak di kawasan cincin api atau lebih sering disebut Pacific Ring of Fire. Hal ini menyebabkan Indonesia menjadi salah satu negara yang rawan akan terjadi bencana alam salah satunya adalah gempa bumi. Ditambah lagi dengan jumlah populasi manusia seiring berjalannya waktu semakin meningkat, hal ini berkebalikan dengan ketesediaan lahan yang semakin sedikit. Maka dari itu, perlu adanya perubahan rencana pembangunan yang awalnya melebar menjadi ke atas atau lebih dikenal dengan sebutan High Rise Building. Namun dalam pembangunannya masih sering terjadi kegagalan struktur. Bangunan tahan gempa menjadi salah satu solusi yang sangat tepat dalam menjawab masalah kegagalan struktur. Ada banyak sekali material yang dapat digunakan, namun ada satu material yang akhir – akhir ini sedang diminati, yaitu baja. Dalam konstruksi modern saat ini, material baja digunakan hampir di setiap jenis struktur antara lain bangunan industri berat, infrastruktur, jembatan, dll. Konfigurasi struktur bangunan baja tahan gempa menurut SNI 1729-2020 dibedakan menjadi 3, yaitu Sistem Rangka Pemikul Momen (Moment Resisting Frame), Sistem Rangka Bresing Konsentrik (Concentrically Braced Frame), dan Sistem Rangka Bresing Eksentrik (Eccentrically Braced Frame). Untuk MRF (Moment Resisting Frame) memiliki kekurangan yaitu kurang kaku untuk memenuhi persyaratan drift control, sedangkan kekurangan CBF (Concentrically Braced Frame) yaitu kemampuan menyalurkan energi yang terbatas. Oleh karena itu digunakan suatu system yang disebut EBF (Eccentrically Braced Frame). Dalam tugas akhir ini, Gedung Perkantoran 8 lantai di Jakarta Barat yang awalnya menggunakan struktur beton bertulang dan terdiri dari 8 lantai, akan dimodifikasi ulang menggunakan struktur baja beton komposit dengan sistem EBF dan disesuaikan jumlah lantai menjadi 15 lantai dengan konfigurasi EBF yang digunakan yaitu Inverted-V Braced. Studi literatur yang digunakan dalam proposal ini mengacu kepada peraturan SNI 1727:2020, SNI 1726:2019, SNI 1729:2020, AISC 341-16, ACI 318-19, buku ajar dan jurnal yang berkaitan dengan struktur komposit dan sistem EBF. Dari hasil analisa yang telah dilakukan, diperoleh hasil yaitu: plat atap dan plat lantai gedung memiliki ketebalan 11 cm. Dimensi balok induk digunakan WF 500x300x11x18, Dimensi balok di luar link digunakan WF 500x300x11x18. Dimensi Link digunakan sebesar WF 400x300x10x16. Dimensi kolom CFT terbesar digunakan CFT 700.700.25. Dimensi kolom beton digunakan 1100x1100 mm. Pondasi direncanakan dengan kedalaman 30 meter menggunakan spun pile dengan diameter 60 cm. Dimensi Sloof digunakan 450x650 mm
======================================================================================================================================
Indonesia is an archipelagic country located in the ring of fire or more commonly known as the Pacific Ring of Fire. This causes Indonesia to become one of the countries that are prone to natural disasters, one of which is earthquakes. Coupled with the increase in the human population over time, this is in contrast to the less available land. Therefore, it is necessary to change the development plan which initially widened to the top or better known as the High Rise Building. However, in its construction there are still frequent structural failures. Earthquake-resistant buildings are one of the most appropriate solutions in addressing the problem of structural failure. There are so many materials that can be used, but there is one material that is currently in demand, namely steel. In today's modern construction, steel is used in almost every type of structure, including heavy industrial buildings, infrastructure, bridges, etc. The configuration of earthquake-resistant steel structures according to SNI 1729-2002 is divided into 3, namely Moment Resisting Frame System, Concentrically Braced Frame System, and Eccentrically Braced Frame System. The MRF (Moment Resisting Frame) has the disadvantage that it is not rigid enough to meet drift control requirements, while the CBF (Concentrically Braced Frame) deficiency is the limited ability to transmit energy. Therefore, a system called EBF (Eccentrically Braced Frame) is used. In this final project, the 8-story Office Building in West Jakarta, which initially used a reinforced concrete structure and consisted of 8 floors, will be re-modified using a composite concrete steel structure with the EBF system and adjusted the number of floors to 15 floors with the EBF configuration used, namely Inverted-V Braced. The literature study used in this proposal refers to SNI regulations 1727:2020, SNI 1726:2019, SNI 1729:2020, AISC 341-16, ACI 318-19, textbooks and journals related to composite structures and EBF systems. From the results of the analysis that has been carried out, the results are obtained, namely: the roof plate and the building floor plate have a thickness of 11 cm. The dimensions of the main beam are used WF 500x300x11x18, the dimensions of the beam outside the link are used WF 500x300x11x18. The Link dimension is used as large as WF 400x300x10x16. The largest CFT column dimensions are used CFT 700,700.25. The dimensions of concrete columns are used 1100x1100 mm. The foundation is planned with a depth of 30 meters using a spun pile with a diameter of 60 cm. Sloof dimensions used 450x650 mm.
