Abstract

Eccentrically Braced Frames (EBF) adalah salah satu struktur baja daktail yang cocok digunakan pada daerah rawan gempa. Link pada EBF yang umum digunakan adalah link horizontal yang memiliki beberapa kelemahan seperti dapat merusak beban berat atau peralatan yang sangat sensitif terutama pada gedung pembangkit listrik sehingga dilakukan penelitian terkait link vertikal. Penelitian ini membahas tentang analisis numerik penggunaan Vertical Shear Link (VSL) dengan menggunakan program bantu ABAQUS. Metodologi penelitian terdiri dari dua tahapan, tahap awal yaitu analisis validasi dari spesimen model eksperimental Zahrai et al. (2015), kemudian hasil analisis validasi tersebut dilakukan perbandingan antara kurva histerisis force displacement model numerik dan kurva histerisis force-displacement model eksperimental. Tahapan selanjutnya adalah melakukan pemodelan dan analisis terkait panjang link dari vertical shear link (VSL) secara sub-assemblage yang didesain dengan batas panjang link yang sesuai. Hasil penelitian menunjukkan bahwa panjang link berpengaruh besar pada daktilitas, kapasitas gaya horizontal, disipasi energi, dan tegangan maksimum yang terjadi pada link. Semakin panjang link, maka kapasitas gaya horizontal, disipasi energi, dan tegangan maksimum yang terjadi akan semakin kecil. Hal ini berbanding lurus pada pelelehan link, dimana dengan panjang link yang semakin pendek, pelelehan akan lebih awal terjadi pada pembebanan

Eccentrically Braced Frames (EBF) is a ductile steel structure that is suitable for use in earthquake-prone areas. The link on the EBF, which is commonly used, is a horizontal link that has several weaknesses, such as being able to damage heavy loads or very sensitive equipment, especially in power plant buildings, so research is carried out regarding vertical links. This study discusses the numerical analysis of the use of Vertical Shear Link (VSL) using the ABAQUS program. The research methodology consists of two stages, the initial stage is validation analysis of the experimental model specimen Zahrai et al. (2015), and then the results of the validation analysis were compared between the force displacement hysteresis curve of the numerical model and the force-displacement hysteresis curve of the experimental model. The next stage is to conduct modeling and analysis related to the link length of the vertical shear link (VSL) by sub assemblage, which is designed with a link length limit in accordance. The results show that the link length has a large effect on the ductility, horizontal force capacity, energy dissipation, and the maximum stress that occurs in the link. The longer the link, the smaller the horizontal force capacity, energy dissipation, and maximum stress. This is directly proportional to link yielding, where with shorter link lengths, yielding will occur earlier on loading
