英文摘要	The replaceable shear links are used as the energy dissipation beam section in the eccentrically braced steel frame and separate from the frame beam. Not only concentrated the inelastic deformation of structure on the energy dissipation beam section, but also achieved the goal that the damaged energy dissipation links can be replaced easily and the repair cost can be reduced after the earthquake. In this paper, the replaceable shear links are researched independently from eccentrically braced steel frames. The experimental study on nine replaceable shear links with different parameters under cyclic loading was carried out. The hysteretic loops, skeleton curve, bearing capacity, displacement ratio, and stiffness degradation of shear links were analyzed. The results show that the hysteretic loops of the replaceable shear links are full and stable. The plastic rotation angles are larger than the limit requirement of 0.08 rad for the energy-dissipating beam section under rare earthquakes, indicating good plastic properties. With the decrease of length and stiffener spacing, the bearing capacity and initial stiffness are improved. The existence of welding holes makes the plastic properties of the specimens be fully developed, so the stiffness degradation is more obvious and the energy dissipation performance is good. The influences of geometric parameters such as section dimension, length ratio, welding hole, and stiffener spacing on the seismic performance of shear links were obtained by parametric analysis. © 2019, Editorial Office of Journal of Building Structures.
