Effect 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...
متن کاملAssessment 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 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 کاملSeismic Yield Displacement Profile in Steel Eccentrically Braced Frames
Displacement-based methods are recognized as appropriate approaches to reach the goals of performance-based seismic design method. In the direct displacement-based seismic design method, the seismic yield displacement is applied as one of the important design parameters. In this paper, a new relation is suggested to determine the lateral displacement pattern at first yielding of eccentrically b...
متن کاملEffect of column-foundation connection stiffness on seismic performance of rocking steel braced frame
Residual drifts after severe earthquakes interrupt serviceability of buildings. Retrofitting of such buildings is in many cases very difficult and consumes lots of time and money. Recently, there are some attempts to develop the seismic design procedures to not only satisfy life safety criteria but also lead to more economical buildings. One of these modern methods of improving seismic performa...
