This paper proposes a simplified analytical model for seismic response prediction of concentrically braced frames. In the proposed approach, a multistory frame model is reduced to an equivalent shear-building one by performing a static pushover analysis. The conventional shear-building model has been improved by introducing supplementary springs to account for flexural displacements in addition...

Indonesia merupakan negara dengan tingkat kegempaan yang cukup tinggi, sehingga gempa seringkali menimbulkan korban jiwa. Untuk mengurangi jiwa akibat gempa, perlu didesain gedung dapat memenuhi kebutuhan performa struktur seperti kekuatan dan daktilitas. Eccentrically Braced Frames (EBF) adalah salah satu baja daktail cocok digunakan pada daerah rawan gempa. Link EBF umum link horizontal memil...

This paper describes the design, testing, and finite element modeling, of a proofof-concept eccentrically braced frame specimen utilizing a hybrid rectangular shear link. The link is self-stabilizing and does not require lateral bracing, making it suitable for use in steel bridge piers where lateral bracing can be difficult to provide (building applications are possible as well). Equations used...

response modification factor (r-factor) is one of the seismic design parameters to consider nonlinear performance of building structures during strong earthquake. relying on this, many seismic design codes led to reduce earthquake loads imposed to the structure. the present paper tries to evaluate the r-factors of conventional concentric braced frames (cbfs) and special moment frames (mrfs) in ...

yielding elements (ye) are among those devices that not only help control structural damages, but make better seismic behavior by concentrating the frames in some removable part of the structures. ye are located at the intersection of concentric braced frame (cbf) in a rectangular shape. in this paper, seismic behavior of the frames with ye will be investigated. for this reason, 5 braced steel ...

Fling-step and forward directivity are two important characteristics of near-field earthquakes. Forward directivity occurs when the rupture propagates toward the site and arises in fault‐normal direction for strike‐slip faults. Fling-step is the consequence of permanent ground displacement imposed by near-field earthquakes and arises in strike-slip faults in the strike parallel direction. Fling...

Finite element analysis was used to investigate the effects of the misalignment of the brace flange-to-beam connection point with the link-end stiffener (referred to as the offset in the paper) on the ductility of eccentrically braced frames (EBF). The offset was speculated to be a possible reason for the unexpected EBF failures observed in the aftermath of the Christchurch earthquake series of...

Indonesia, which has tectonic conditions in the form of a large meeting point world's plates and several small plates, makes region Indonesia center earthquake occurrences earthquake-resistant buildings are an absolute necessity. Eccentrically Braced Frames (EBFs) model steel building structures that can limit inelastic behavior only to link elements, where use these links, especially replaceab...
