Assessing Seismic Behavior of Eccentrically Braced Frames (EBFs) Due to Near-Field Ground Motions.
Abstract eng: Near-field ground motions have caused much damage in vicinity of seismic sources during recent earthquakes. Eccentrically braced frames have convinced ductility and enough stiffness. This research aims to: investigate the nonlinear dynamic and nonlinear static response of buildings with EBFs due to near-field and far-field ground motions and compare the results for EBFs with short and EBFs with long link beams. To obtain this objective, 3-D steel buildings in 3, 5, 8 and 15 stories by short and long link beams were modeled. 9 near-fields with 3 far-field ground motions were utilized as input ground motions. It is found that in near-field regions, the demands of structures have larger values as compared with far-field regions. Based on nonlinear analysis, the values of story displacement, inter-story drift, story acceleration and velocity, base shear, for shear link-beams systems and moment link-beams systems under both near and far-field earthquakes were investigated and the results have been discussed.
