Abstract
Indonesia merupakan negara dengan aktivitas kegempaan yang sangat tinggi. Hal ini dikarenakan Indonesia merupakan Negara kepulauan yang terletak pada pertemuan tiga lempeng tektonik aktif dunia yaitu Lempeng Eurasia, Lempeng Indo-Australia dan Lempeng Pasifik. Dampak yang ditimbulkan dari gempa bumi sangatlah besar, baik dari kerugian material maupun jatuhnya korban jiwa. Pada umumnya, timbulnya korban disebabkan karena tertimpa reruntuhan gedung. Sehingga untuk meminimalisir dampak dari bencana gempa bumi, struktur gedung harus didesain tahan gempa.
Baja merupakan alternatif material untuk bangunan tahan gempa yang sangat baik. Jika dibandingkan dengan struktur beton, baja dinilai memiliki sifat daktilitas yang dapat dimanfaatkan pada saat struktur memikul beban akibat gempa. Salah satu sistem pada bangunan baja yang dirancang menahan gempa adalah sistem struktur rangka bresing eksentrik atau yang biasa disebut dengan eccentrically braced frame (EBF). EBF biasa disebut sebagai sistem hybrid antara system rangka pemikul momen dan concentrically braced frame (CBF) karena EBF mampu memikul kombinasi antara beban rangka dan truss. EBF memiliki daktilitas tinggi seperti sistem rangka pemikul momen, tetapi juga memiliki kekakuan yang tinggi seperti CBF. Filosofi desain EBF adalah mekanisme runtuh akan terjadi pada link sedangkan elemen lainnya tetap dalam kondisi elastik.
Dalam tugas akhir ini, Gedung Dental Learning Center dimodifikasi menjadi menggunakan struktur baja sistem EBF yang memiliki 20 lantai dengan 1 basement. Konfigurasi EBF menggunakan inverted V Braced dan akan memenuhi persyaratan keamanan struktur berdasarkan SNI 1729:2015, SNI 1726:2019, SNI 2847:2020, SNI 1727:2020, dan AISC 341-10.
Dari Analisa dan perhitungan yang telah dilakukan didapatkan hasil perencanaan tebal plat lantai sebesar 11 cm dan 13 cm dengan material beton mutu f’c 30 MPa. Dimensi balok induk menggunakan WF 500x300x11x18. Dimensi kolom menggunakan CFT (Concrete Filled Tube) 700x700x25, CFT 650x650x25 dan CFT 600x600x25. Struktur diperkaku dengan EBF dengan panjang link 150 cm (Short Link) dan bracing berdimensi WF 300x300x15x15, pada lantai Ground Floor digunakan material beton f’c 30 MPa dengan Kolom 1200x1200, Balok Induk 450x650, Balok Anak 400x600, Dinding basement dengan tebal 250 mm dan plat basement dengan tebal 250 mm. Dimensi sloof menggunakan 500x800mm. Pondasi direncanakan dengan spun pile D80 dengan kedalaman 17m
===============================================================================================
Indonesia is a country with very high seismic activity. This is because Indonesia is an archipelagic country located at the confluence of three active tectonic plates in the world, namely the Eurasian Plate, the Indo-Australian Plate and the Pacific Plate. The impact of the earthquake is very large, both from material losses and loss of life. In general, the number of victims was caused by falling debris from the building. So to minimize the impact of an earthquake, the building structure must be designed to withstand earthquakes.
Steel is an excellent alternative material for earthquake-resistant buildings. When compared to concrete structures, steel is considered to have ductility properties that can be utilized when the structure is carrying loads due to earthquakes. One of the systems in steel buildings designed to withstand earthquakes is the eccentrically braced frame (EBF) system. EBF is commonly referred to as a hybrid system between a moment-bearing frame system and a concentrically braced frame (CBF) because EBF is capable of carrying a combination of frame and truss loads. EBF has high ductility like moment resisting frame systems, but also has high stiffness like CBF. The EBF design philosophy is that the mechanism of collapse will occur in the link while the other elements remain in an elastic state.
In this final project, the Dental Learning Center Building was modified to use the EBF system steel structure which has 20 floors with 1 basement. The EBF configuration uses an inverted V Braced and will meet the structural safety requirements based on SNI 1729:2015, SNI 1726:2019, SNI 2847:2020, SNI 1727:2020, and AISC 341-10.
From the analysis and calculations that have been carried out, the results of the planning for the thickness of the floor slab are 11 cm and 13 cm with f'c 30 MPa quality concrete material. Dimensions of the main beam using WF 500x300x11x18. Column dimensions use CFT (Concrete Filled Tube) 700x700x25, CFT 650x650x25 and CFT 600x600x25. The structure is reinforced with EBF with a link length of 150 cm (Short Link) and bracing with dimensions of WF 300x300x15x15, on the Ground Floor concrete material f'c 30 MPa is used with Columns 1200x1200, Main Beams 450x650, Secondary Beams 400x600, basement walls with a thickness of 250 mm and basement plate with a thickness of 250 mm. The dimensions of the sloof use 500x800mm. The foundation is planned with spun pile D80 with a depth of 17m
