Investigation of Steel Frames Equipped with Steel Eccentric Braces and Steel-Concrete Buckling-Restrained Braces Having Moment Link

Background: Different bracing systems of steel Eccentric Braces (EBs) and steel-concrete Buckling-Restrained (BRBs) can be used in frames order to make the stronger resisting lateral loads. These with EBs or BRBs are generally called Eccentrically Braced Frames (EBFs) (BRBFs), respectively. Objective: This study aims investigate having moment link. Methods: The EBFs BRBFs nonlinearly analysed employing finite element software ABAQUS. Experimental tests EBF BRB utilised for validation their modelling. modelling is validated by comparing results experimental results. Then, an a BRBF designed extreme earthquake records Tabas, Chi-Chi, Northridge selected dynamic analyses BRBF. method applied analyse under records. Results: achieved from displacements, base shears, energy dissipations link rotations. compared discussed. Conclusion: It concluded that hierarchy displacements BRBF, link, related because directly proportional peak ground accelerations records, there same terms accelerations.

Moreover, improves shear capacities frame Consequently, demonstrated superior structural performance point view. Thus, more efficiently structures large loads
