Abstract
Penelitian ini bertujuan untuk menganalisis pengaruh variasi stiffener pada sambungan haunched bolted extended end plate terhadap kapasitas sambungan dan daktilitasnya. Empat variasi stiffener dianalisis, yaitu (1) satu stiffener di atas, (2) dua stiffener di atas dan bawah, (3) empat stiffener pada sisi atas, bawah, kiri, dan kanan, serta (4) kombinasi stiffener segitiga dan memanjang pada sambungan. Profil balok yang digunakan adalah WF 400×200×8×13 dan kolom WF 500×200×10×16 dengan mutu baja SS400 serta baut M20 mutu A325. Analisis dilakukan untuk mengetahui fungsi masing-masing variasi stiffener, menghitung kebutuhan luas penampang minimum yang diperlukan, serta mengevaluasi perilaku daktilitas sambungan berdasarkan nilai perpindahan ultimit dan leleh dari hasil simulasi numerik. Hasil penelitian menunjukkan bahwa penambahan jumlah stiffener secara signifikan meningkatkan kapasitas sambungan dan mengurangi deformasi lokal pada end plate, terutama pada variasi dengan empat stiffener yang mampu mendistribusikan gaya lebih merata. Namun demikian, seluruh variasi stiffener pada penelitian ini belum direkomendasikan untuk diimplementasikan dalam desain struktur baja karena kegagalan masih terjadi pada baut sambungan, yang menunjukkan bahwa sambungan belum memenuhi ketentuan kekuatan dan daktilitas SRPMK. Permodelan sambungan pada studi ini belum dapat dijadikan referensi desain praktis karena diperlukan modifikasi lebih lanjut, seperti penggunaan balok dengan reduce beam section untuk melokalisasi kegagalan pada balok, bukan pada sambungan. Penelitian ini menekankan pentingnya pemilihan variasi stiffener yang tepat, perbaikan desain sambungan, serta verifikasi eksperimental lebih lanjut untuk memastikan kapasitas dan daktilitas sambungan memenuhi persyaratan standar desain struktur baja yang berlaku di Indonesia.

This study aims to analyze the effect of stiffener variations on the haunched bolted extended end plate connection in terms of joint capacity and ductility. Four stiffener configurations were investigated: (1) one stiffener at the top, (2) two stiffeners at the top and bottom, (3) four stiffeners on the top, bottom, left, and right sides, and (4) a combination of triangular and longitudinal stiffeners in the connection. The beam used was WF 400×200×8×13 and the column was WF 500×200×10×16, both made of SS400 steel, with M20 A325 bolts. The analysis aimed to determine the function of each stiffener variation, calculate the minimum required cross-sectional area, and evaluate the ductility behavior based on ultimate and yield displacements obtained from numerical simulations. The results showed that increasing the number of stiffeners significantly improves connection capacity and reduces local deformation on the end plate, especially in the variation with four stiffeners which distributes forces more evenly. However, all stiffener variations in this study are not yet recommended for implementation in steel structure design, as failure still occurs in the bolts, indicating that the connections do not fulfill SRPMK strength and ductility requirements. The connection modeling in this study cannot yet be used as a practical design reference because further modifications are needed, such as using beams with a reduce beam section to localize failure in the beam rather than in the connection. This study emphasizes the importance of selecting appropriate stiffener variations, improving connection designs, and conducting further experimental verification to ensure that the connection capacity and ductility comply with applicable steel structure design standards in Indonesia
