“…Eccentrically Braced Frames (EBF) dengan horizontal link (H-EBF), link menjadi satu kesatuan dengan balok sehingga melakukan perbaikan atau penggantian link yang mengalami kerusakan pada H-EBF pasca terjadinya gempa besar bisa sangat sulit dan mengganggu sistem struktur lain [4]. Berdasarkan kelemahan dari H-EBF tersebut, maka digunakan V-EBF dimana pada V-EBF memungkinkan untuk perbaikan atau penggantian elemen link yang rusak pasca terjadi gempa besar, tanpa mengganti atau mengubah bagian dari balok [5]. V-EBF merupakan sistem Eccentrically Braced Frames dimana link dipasang secara vertikal mengubungkan bracing dengan balok.…”

“…Concentrically Braced Frame is a type of braced frame with a high stiffness but less ductile. Eccentrically Braced Frame (EBF) is a structural steel frame system that has good ductility and high stiffness in receiving lateral forces, [1], [2], [3]. EBF has a combination of MRF and CBF properties that meet the criteria of the structure in terms of strength, stiffness, and ability to absorb dissipation energy [4].…”

Eccentrically Braced Frame (EBF) is an excellent steel frame system for resisting earthquake forces. This frame shows good performance in terms of stiffness and has excellent ductility. When it is subject to a severe seismic event, the links undergo inelastic deformations and become the primary source of energy dissipation. However, the performance of EBF is strongly influenced by the length of the links that are an essential part of the EBF system. Links should be limited not be too short or too long because it relates to the stiffness and ductility of the frame. The study of EBF on the 80-90s also limits the ratio both of e/L not exceed 0.5 and the diagonal brace angle between 40°-60°. This research will review the influence of the length of the links varied from the e/L ratio of 0.005 to 0.38. This variation will divide the links into three types of yielding, i.e., the short link, intermediate link with shear dominance, and intermediate link with bending dominance. In this study, the behavior of various link lengths on Eccentrically Braced Frame will be evaluated using finite element analysis using MSC Patran and Nastran. The structure is modeled as a one-dimensional D-Braced EBF type that is given static monotonic load with displacement control. The results obtained in the form of loaddisplacement curves which will be analyzed in strength and ductility. In addition, an ultimate load normalization curve will be generated to obtain the load pattern for the various link length. The curve shows that the ultimate load on the EBF will decrease if there is an increase in link length. The significant decrease occurs when e/L > 0.2.

“…Eccentrically braced frames (EBFs) had been accepted as a type of hybrid structural system with good lateral stiffness and ductility [6]. During a rare earthquake, the main structures (e.g., columns, beams outside of shear links, and braces) are always in the elastic stage, and the shear links in the EBFs are usually designed to allow high ductility and shear failure and dissipate seismic energy [7], which would be only repaired to restore the structural performance [8].…”

A new type of prefabricated reinforced concrete-Y-shaped eccentrically steel brace structure (PRC-Y-ESBS) is developed by combining the mechanical property of prefabricated reinforced concrete frame and Y-shaped eccentrically steel brace, so the seismic performance and seismic resilience capacity of prefabricated reinforced concrete frame can be effectively improved. In the PRC-Y-ESBS, the precast concrete beam-to-shear link composite connection should have enough bearing capacity and resilience capacity under the shear force and bending moment, so the damage can be restricted in shear links. In this paper, an innovative precast concrete beam-to-shear link composite connection (PCB-SLCC) with bending moment and shear force separate method is proposed. Four different types of shear connectors are analyzed in detail by using the verified numerical method, and the shear capacity and failure mode of shear connectors can be obtained. Then, the innovative PCB-SLCCs with the reasonable shear connector considering different influencing parameters are also studied in detail. The results indicate that the shear connectors and high-strength bolts are still in elastic state at ultimate load, and little damage has occurred in the concrete between the embedded plate and precast concrete frame, while the PCB-SLCC has enough bearing capacity at the ultimate stage. In addition, this study also clearly identifies that high-strength bolts can only bear the bending moment, and the shear force is only carried by shear connectors, so the bending moment and shear force of the innovative PCB-SLCC with high bearing capacity, ease of installation, and seismic resilience capacity can be apparently separated.
