The Dog Bone Type Seismic Performance Analysis Of Eccentrically Braced Steel Frame

With the rapid development of Chinese economic level at the same time, thesteel frame structure has continued going on in our lives the high-rise eccentricallybraced steel frame, earthquake than steel braced frame has the ductility and energydissipation capacity enough in the rare high-rise eccentrically braced steel frame,under small earthquake than steel frame more can meet the requirements of bearingcapacity and stiffness of the high-rise eccentrically braced.This paper uses the method of SAP2000finite element software model, the steelframe of EBSF yield model to study the dog bone type eccentric support, an idealmodel is obtained through the deformation mechanism, respectively, using threedifferent forms of support, the structure of the bearing capacity, stiffness, ductility andseismic performance are analyzed, that accord with the practical engineering project;also joined the bone dog type design, by changing the support and the dog bone typeflange beam layout, structure analysis of different arrangement of bearing capacity,stiffness, ductility performance, concluded that the best scheme. Use SAP2000toanalysis data and theoretical comparison, error layer arrangement can improve thestress performance of the structure components, inter story displacement angle isrelatively small so that members can give full play to the properties of the material,saves a large amount of steel, environmental protection, and provide data for thepractical engineering, and reference for future project reference.
