Abstract:It is convenient and economical to repair eccentrically braced steel frames with replaceable shear links after an earthquake, but few studies have focused on it domestically and internationally. Therefore, 16 groups of web-connected shear links connected by bolts with eccentrically braced steel frames were designed and analyzed through numerical simulations. The effect of changing the parameters (section size, length of the energy dissipation section, stiffener spacing, stiffener arrangement, and comprehensive parameters) on the hysteretic performance and the skeleton curve of web-connected shear links under low-cyclic reversed loading was discussed, and the simplified restoring force model of shear links was established. The results show that section size is the parameter that primarily influences the energy dissipation of the web\|connected shear links. The proposed restoring force model is in good agreement with the simulated skeleton curve, which can be used as a reference for elastic-plastic analysis of such shear links.
