Topic : Analysis of Different Link Length in Eccentric Braced Frames

Authors:Ashwani Bhaskar || Dr.Kailash Narayan

Abstract:Regions prone to seismic disturbances are designed in such a way that its stiffness should be maintained during moderate earthquakes and it should absorb and it should dissipate a large amount of the energy during severe earthquakes. The conventional framing system required heavy sections to fulfilthe stiffness criteria and ductile capacity. the concentrically braced frames show good results in stiffness but poor results in ductility hence resulting in bad energy dissipation. The current study deals with the eccentrically Braced Steel Frames (EBF). EBF configuration is similar to conventional braced frames with the exception that one of the ends must be connected eccentrically to the frame. The energy dissipation is achieved through the yielding of a beam segment known as the link. EBF is economical and satisfies both the stiffness as well as the ductility requirement. In the present study eccentrically, braced steel frames are used with increasing link of 0 mm, 500 mm, 1000 mm and 2000 mm. The building is a 21-story building with bracings provided at the corners. Various parameters such as Maximum story drift, Stiffness, Torsion, Natural time period are calculated for each floor using ETABS..

Keywords: Eccentric Braced Steel Frames,Link Length,Pushover Analysis, ETABS etc.
