Abstract

Penelitian ini membahas analisis efisiensi struktur baja menggunakan sistem Eccentrically Braced Frame (EBF) dengan link vertikal dan horizontal pada bangunan Rumah Sakit Sumber Kasih di Kota Cirebon. Tujuan utama penelitian adalah membandingkan kinerja dan efisiensi penggunaan material baja antara kedua tipe EBF sebagai upaya menghasilkan struktur yang lebih ekonomis dan tahan gempa. Tiga model struktur dianalisis: model eksisting tanpa bracing, model dengan EBF link horizontal, dan model dengan EBF link vertikal. Seluruh pemodelan dan analisis menggunakan perangkat lunak ETABS dan mengacu pada standar SNI terkait ketahanan gempa serta perencanaan struktur baja. Metode yang digunakan adalah metode respon spektrum untuk pembebanan gempa, dengan evaluasi meliputi kontrol gaya geser dasar, simpangan antar lantai, pengaruh P-Delta, serta level kinerja struktur. Hasil penelitian menunjukkan bahwa penggunaan sistem EBF Link Horizontal menghasilkan efisiensi massa baja sekitar 2.79% atau pengurangan sekitar 19.69 ton dari struktur existing, sedangkan penggunaan EBF Link Vertikal menghemat sekitar 2.48% atau 17.58 ton. Perbedaan massa antara sistem EBF link horizontal dan vertikal dengan profil baja yang identik sangat kecil, hanya sekitar ±0,3%. Dari sisi kinerja, baik EBF link horizontal maupun vertikal sama-sama mencapai level Immediate Occupancy. EBF Link Horizontal memberikan peningkatan kinerja struktur sebesar 24.27% pada arah X dan 43.55% pada arah Y, dibanding EBF Link Vertikal yang memberikan peningkatan 15.44% pada arah X dan 15.51% pada arah Y. This study discusses the analysis of steel structure efficiency using an Eccentrically Braced Frame (EBF) system with vertical and horizontal links in the Sumber Kasih Hospital building in Cirebon City. The main objective of this study is to compare the performance and efficiency of steel material usage between the two types of EBF as an effort to produce a more economical and earthquake-resistant structure. Three structural models were analyzed: the existing model without bracing, the model with horizontal EBF links, and the model with vertical EBF links. All modeling and analysis were conducted using ETABS software and adhered to SNI standards related to earthquake resistance and steel structure design. The method employed was the response spectrum method for earthquake loading, with evaluations including base shear control, inter-story drift, P-Delta effects, and structural performance levels. The research results show that the use of the horizontal EBF link system achieves steel mass efficiency of approximately 2.79% or a reduction of approximately 19.69 tons from the existing structure, while the use of the vertical EBF link saves approximately 2.48% or 17.58 tons. The mass difference between the horizontal and vertical EBF link systems with identical steel profiles is very small, only approximately ±0.11%. In terms of performance, both the horizontal and vertical EBF links achieve the Immediate Occupancy level. The Horizontal EBF Link provides a structural performance improvement of 24.27% in the X direction and 43.55% in the Y direction, compared to the Vertical EBF Link, which provides an improvement of 15.44% in the X direction and 15.51% in the Y direction
