ASSESSMENT OF SEISMIC BEHAVIOR FOR ECCENTRIC BRACED FRAME WITH VERTICAL LINK

Abstract

This research is concerned with studying seismic behavior of steel eccentric braced frames with vertical link considering several parameters, such as: number of stories, number of bays, length of link, and ground accelerations. Through this study, Response Modification factor is investigated for these models considering two analysis methods: pushover analysis and time history analysis. The results show that short link gives more ductility compared with long link. Values of response modification factor increases as peak ground acceleration increases for the same height of building, number of stories, and number of bays. Finally, it is concluded that using one value for response modification factor is not acceptable for number of frames in different cases.
