Abstract: The traditional Y-eccentrically braced steel-concrete composite frame with single shear link (SY-EBCF for short) has been proven to be an effective energy dissipation structure system. However, the introduction of shear link will significantly compress the building space and reduce the building function. Based on the SY-EBCF, the Y-eccentrically braced steel-concrete composite frame with double shear links (DY-EBCF for short) is proposed in this paper, which can ensure sufficient bearing capacity and lateral stiffness of the eccentric brace system while minimizing the occupation of shear link on the lower space by increasing the number of shear link and reducing the size of shear links. To investigate the mechanical performance of the DY-EBCF, a dedicated test specimen was designed and fabricated, followed by a pseudo-static experiment. The failure mode, hysteretic behavior, and sectional strain development were thoroughly analyzed. The test results indicate that the shear link mainly relies on shear deformation of the web plate to dissipate energy, andrior to the failure of the shear link, the structure exhibits stable hysteretic behavior and demonstrates excellent energy dissipation capacity. When the damaged link is removed, the structure is able to return to its un-deformed original position under the action of unbalanced internal forces. Upon removal of the failed link, the residual drift angle of the specimen was recorded as 0.002 rad, which is well below the code limitation (0.005 rad). Although the lateral bearing capacity of the residual composite frame decreases to 1/2 of that of DY-EBCF, the structure still has stable load-bearing capacity. The test results of DY-EBCF and SY-EBCF were compared, showing that DY-EBCF has better seismic performance in terms of energy dissipation, stiffness and deformation capacity.
