Assessment of Seismic Behavior of Eccentrically Braced Frame with Double Vertical Link (dv-ebf)
This paper is an experimental study on the behavior of vertical shear link in the single and double configurations. There have been three specimens selected for examining the effects of different details .The first specimen was an I section with no stiffener, while the second specimen composed of I section with stiffeners designed according to AISC 2005. Third specimens were composed of two I s...
متن کاملNumerical study on the behavior of link-to-column connections in eccentrically braced frames
Geometry of eccentrically braced frames (EBFs) in some cases causes the connection of link beam to the column. The details of such conditions should be studied carefully due to the full plastic rotation in the link beam. In this research, the behavior of link-to-column connection is modeled and the failure modes are considered. Based on the previous researches shear link can exhibit better beha...
متن کاملEffect of Link - Beam Stiffener and Brace Flange Alignment on Inelastic Cyclic Behavior of Eccentrically Braced Frames
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...
متن کاملSeismic Behavior of Direct Displacement-based Designed Eccentrically Braced Frames
Direct Displacement-Based Design (DDBD) is a performence-based seismic design method that has been proposed and well developed over the past two decades to design RC frame structures, shear walls and bridges. In this method, the behavior of a multi-degree-of-freedom (MDOF) sysytem is approximaeted by an equivalent single-degree-of-freedom (SDOF) substitute structure. Although this method has be...
متن کاملEffect of Fling-Step on Seismic Response of Steel Eccentrically Braced Frame Structures
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...
