چکیده مقاله
The design of an eccentrically braced frame is based on creating a frame which will remain essentially elastic outside a well define link There are two type eccentrically braced frame, eccentrically braced frame with vertical link and horizontal link One of the exclusion of plastic deformation from the main stricture result on no damage in the roof of the structures under severs earthquakes, easy and simple rehabilitation, and the replacement of link father earthquake Use vertical link in the eccentrically braced frame prevent rotation mean beam and cause decreased damage in the main structure In the study, 3 D steel building in 4, 8 and 12 story by short link beams was modeled Short link beam considered to 0 5 m, 4, 8 and 12 numbers of stories In paper, non linear static analyses and non linear dynamic performed It was observed that use vertical link in the EBF prevented rotation mean beam Also use vertical link in the EBF decreased base shear, relative acceleration and relative velocity in the structures It was observed that eccentrically braced frame with vertical link yields less displacement and so the energy dissipation capacity increased
