Evaluation on eccentrically braced frame with single and double shear panels

In the present study, Eccentrically Braced Frames' (EBF) seismic behavior with single and double shear panels is introduced. The numerical modeling is done by commercial FE software (Abaqus) under two kinds of cyclic displacement loads (including pushover), to evaluate shear links' behavior. The effects of concrete slab are studied on overall frame behavior, and the ductility coefficient increase for double shear panel models is investigated. The models were exposed to time-history analysis via scaled earthquake records, to study the models' energy parameters. Imparting acceleration on the structure and carrying out time history analysis, the double shear panel system revealed a higher tendency to form shear links, causing greater dissipation capacity in the plastic zone. In pushover and time history analyses, it was demonstrated that concrete slab can have a destructive impact on frame and shear link behavior.
