This paper describes the results of an experimental study to verify proposed design requirements for eccentrically braced frame links with hollow rectangular i.e., tubular cross sections. Twelve primary link specimens and two supplementary links that have different end connections are tested. Three cross sections and four normalized link lengths are considered. Two of the cross sections have we...

The present study sets out to integrate the performance-based seismic design approach with the connection topology optimization method. Performance-based connection topology optimization concept aims to simultaneously optimize the size of members and the type of connections with respect to the framework of performance-based seismic design. This new optimization concept is carried out for unbrac...

in this study, for evaluating ductility of ordinary concentrically braced frames (ocbfs) and special concentrically braced frames (scbfs) which are x- braced in two adjacent middle spans, 16 steel ordinary concentrically braced frames and 16 special concentrically braced frames are studied. the results confirm that, although most of ordinary concentrically braced frames, which are x-braced, can...

The seismic events that occurred in the last decades have highlighted importance of a correct design structures areas and inadequacy large part built heritage. Modern codes are still lacking terms prescriptions for evaluation performance existing buildings. present work proposes simplified method demand plastic rotation short links steel Eccentrically Braced Frames (EBFs). A relationship demand...
