Abstract

Peningkatan kebutuhan akan sarana pendidikan yang representatif mendorong perencanaan bangunan yang tidak hanya fungsional, tetapi juga aman terhadap beban gempa. Gedung perkuliahan sebagai salah satu fasilitas utama dalam dunia pendidikan harus dirancang dengan memperhatikan aspek kekuatan struktur dan kenyamanan pengguna. Pemilihan struktur rangka baja menjadi alternatif yang menjanjikan karena karakteristiknya yang ringan, kuat, dan mudah dirakit. Untuk meningkatkan performa terhadap gaya lateral, sistem rangka breising eksentris dipilih sebagai sistem penahan beban gempa yang mampu mengontrol deformasi sekaligus menyediakan energi disipasi yang baik.
Dalam perencanaan ini, dilakukan analisis struktur terhadap gedung perkuliahan empat lantai dengan sistem rangka baja dan rangka breising eksentris. Proses dimulai dengan pengumpulan data pembebanan berdasarkan SNI 1727:2020 untuk beban gravitasi dan SNI 1726:2019 untuk beban gempa. Pemodelan struktur dilakukan menggunakan perangkat lunak ETABS untuk menganalisis perilaku struktur secara menyeluruh, termasuk pengecekan kekuatan elemen struktur, stabilitas global, dan simpangan antar lantai. Profil baja yang digunakan dirancang sesuai ketentuan SNI 1729:2020 untuk menjamin kekuatan dan keselamatan struktur.
Dari analisa dan perhitungan yang telah dilakukan didapatkan hasil perencanaan untuk kolom digunakan profil kingcross 500.300.12.19 dan kingcross 400.200.12.16, balok induk menggunakan profil WF 500.200.10.16 dan WF 400.200.12.16. Struktur diperkaku dengan rangka bresing eksemtris dengan panjang link 100 cm (short link), dan bresing menggunakan profil WF 250.250.8.12. Tebal pelat lantai direncanakan dengan tebal 12 cm, kolom pedestal berdimensi 700 x 700 mm, dan sloof berdimensi 400 x 600 mm, digunakan material beton bermutu 30 Mpa untuk masing masing elemen struktur tersebut. Pondasi direncanakan menggunakan spun pile dia. 40 cm dengan kedalaman 12 m.

The increasing demand for representative educational facilities drives the planning of buildings that are not only functional but also safe against seismic loads. Lecture halls, as one of the primary facilities in the education sector, must be designed with attention to structural strength and user comfort. Steel frame structures are considered a promising alternative due to their lightweight, high strength, and ease of assembly. To improve seismic performance, the eccentrically braced frame (EBF) system is selected as a lateral load-resisting system capable of controlling deformation while providing effective energy dissipation.
In this project, a structural analysis was conducted for a four-story lecture building using a steel frame and an eccentrically braced frame system. The process began with load data collection based on SNI 1727:2020 for gravity loads and SNI 1726:2019 for seismic loads. The structural modeling was carried out using ETABS software to analyze the overall behavior of the structure, including strength checks of structural elements, global stability, and inter-story drift limits. The steel profiles were designed according to SNI 1729:2020 to ensure structural safety and adequacy.
Based on the analysis and calculations conducted, the structural design resulted in the use of Kingcross 500.300.12.19 and Kingcross 400.200.12.16 profiles for the columns. The main beams use WF 500.200.10.16 and WF 400.200.12.16 profiles. The structure is braced with an eccentric bracing system using a 100 cm long link (short link), and the bracing elements use WF 250.250.8.12 profiles. The floor slab is designed with a thickness of 12 cm. The column pedestals are dimensioned at 700 x 700 mm, and the tie beams (sloof) are dimensioned at 400 x 600 mm. Concrete with a strength of 30 MPa is used for each of these structural elements. The foundation is designed using spun piles with a diameter of 40 cm and a depth of 12 meters.
