Abstract

Proyek pembangunan Gedung Teaching Industry Learning Center (TILC) merupakan salah satu proyek pembangunan gedung riset dan perkuliahan yang diadakan oleh Sekolah Vokasi Universitas Gadjah Mada (SV UGM. Sementara itu, kondisi geologis Kepulauan Indonesia secara umum, maupun Yogyakarta secara khusus menunjukkan bahwa Gedung TILC UGM berada di lokasi yang memiliki kerawanan tinggi terhadap gempa bumi, sehingga nantinya Gedung TILC UGM akan menerima gaya gempa yang cukup besar. Maka dari itu, diperlukan modifikasi pada struktur Gedung TILC UGM agar memiliki ketahanan yang lebih baik terhadap gempa bumi. Salah satu modifikasi yang direncanakan pada Gedung TILC UGM adalah perubahan material utama dari beton bertulang menjadi baja – beton komposit, dan dengan penambahan sistem Eccentrically Braced Frame (EBF). Material baja – beton komposit memberikan keunggulan diantaranya penghematan berat baja, peningkatan kekuatan pelat lantai, peningkatan kapasitas pikul beban, dan penambahan bentang pada bentang tertentu. Sistem Eccentrically Braced Frame (EBF) memberikan keunggulan diantaranya memberikan kekakuan elastik tinggi, memberikan respon inelastik stabil di bawah pembebanan lateral siklik, dan memberikan kemampuan disipasi energi dan daktilitas yang baik. Pada tugas akhir ini direncanakan modifikasi Gedung TILC UGM menggunakan baja – beton komposit dan sistem EBF yang dimulai dari pengumpulan data, preliminary design, desain struktur sekunder dan kontrolnya, pemodelan dan analisis struktur, desain struktur primer dan kontrolnya, desain sambungan, desain pondasi, dan terakhir melakukan penggambaran hasil perencanaan. Perencanaan modifikasi gedung TILC UGM menggunakan acuan SNI 1729:2015 tentang Spesifikasi Untuk Bangunan Gedung Baja Struktural dan peraturan – peraturan lainnya. Dari hasil analisis dan perencanaan modifikasi ini, didapatkan pelat lantai dengan tebal 12 cm dengan material beton fc’ 30 MPa dan bondex. Lalu digunakan pula balok anak lantai dan atap dengan profil WF 350.250.9.14. untuk elemen struktur primer diantaranya balok induk menggunakan profil baja WF 700.300.15.28, WF 700.300.13.24, WF 700.300.13.20, dan WF 450.300.10.15 yang direncanakan sebagai balok komposit, dan untuk kolom menggunakan kolom komposit dengan profil CFT 700.700.25, CFT 700.700.16, dan CFT 650.650.25. Struktur diperkaku dengan sistem EBF, dengan balok link sepanjang 1 m (link pendek) yang menggunakan profil WF 700.300.15.28, WF 700.300.13.24, dan WF 700.300.13.20; serta bresing eksentris yang menggunakan profil WF 300.300.15.15. Sambungan-sambungan direncanakan menggunakan sambungan baut dan las. Struktur bawah terdiri dari sloof yang berukuran 500 x 800 mm, lalu poer dengan ukuran 4 x 4 m setebal 1,5 m, dan 4 tiang pancang/spun pile pada setiap poer sedalam 26 m dengan diameter D80. ================================================================================================ The construction project of the Teaching Industry Learning Center (TILC) building is one of the research and learning building construction projects carried out by Sekolah Vokasi Universitas Gadjah Mada (SV UGM). Meanwhile, the geological conditions of the Indonesian Archipelago in general, as well as Yogyakarta in particular, indicate that the TILC UGM Building is located at a location that is prone to earthquakes, so that later the TILC Building will receive a large earthquake force with a large chance of occurrence. Therefore, it is necessary to modify the structure of the TILC Building in order to get a better resistance to earthquakes. One of the modifications planned at the TILC Building is a change in the main material from reinforced concrete to steel - concrete composite, and with the addition of the Eccentrically Braced Frame (EBF) system. Steel – concrete composite material provide advantages including savings in steel weight, increased strength of floor slabs, increased load bearing capacity, and increased span in certain spans. The Eccentrically Braced Frame (EBF) system provides advantages including high elastic rigidity, provides a stable inelastic response under cyclic lateral loading, and provides good energy dissipation and ductility. In this final project, it is planned to modify the TILC Building using steel – concrete composite and the EBF system starting from data collection, preliminary design, secondary structure design and control, structural modeling and analysis, primary structure design and control, joint design, foundation design, and finally, drawing the planning results to technical drawings. The planning for modification of the TILC building uses the SNI 1729: 2015 reference regarding the Specifications for Structural Steel Buildings, and other regulations. From the results of analysis and modification plan, we have floor slabs with thickness of 12 cm, with material used are fc’ 30 MPa concrete and bondex floor deck. Using floor and roof joists with steel profile of WF 350.250.9.14. For the primary structural elements, the main beams using the steel profiles of WF 700.300.13.28, WF 700.300.13.24, WF 700.300.13.20, and WF 450.300.10.15 which planned as composite beams. The main columns are planned as composite columns of CFT which using the profiles such as CFT 700.700.25, CFT 700.700.16, and CFT 650.650.25. The structure is stiffened by EBF system which has 1 m links (short links) using WF 700.300.15.28, WF 700.13.24, and WF 700.300.13.20, and eccentrical bracings with the profile WF 300.300.15.15. The connections are planned as bolt and welding connections. The substructure contains sloofs with the dimension of 500 x 800 mm, 4 x 4 meter pilecaps with 1,5 meter thickness, and 4 spun piles at each pilecap with the depth of 26 m and diameter D80.
