The beam-column joint with replaceable energy dissipators has the advantages of convenient and economical repair after an earthquake. For a bending shear replaceable component with simple structure, easy construction, stable energy consumption capacity, and consistent tensile and compressive mechanical properties, a refined finite element model of flexural-shear replaceable energy dissipators was established. Then, the failure mode, hysteresis curve, skeleton curve and stress distribution state of the component were analyzed. The influence of parameters such as height-width ratio, width-thickness ratio of limb columns for replaceable energy dissipators, and overall slenderness ratio of energy dissipation zone was considered, and the effects on skeleton curves, stiffness and equivalent viscous damping coefficient of energy dissipators were systematically discussed. The analysis results showed that when the height-width ratio of limb columns in energy dissipators was greater than 4.0, the limb columns were prone to buckling behavior, and the recommended threshold value of the height-width ratio is 1.3~4.0. Increasing the width-thickness ratio of the energy dissipators decreases the initial stiffness and bearing capacity of the specimen, and it was recommended that the width-thickness ratio of limb columns should be no more than 2.5. When the slenderness ratio of the energy dissipation zone was large, its out-of-plane stability and energy dissipation capacity would be weakened, it is suggested the slenderness ratio of the energy dissipation zone not exceed 48. When height-width ratio of limb columns were less than 1.0 and greater than 2.5, the error between the theoretical prediction and the finite element calculation of the yield strength for flexural-shear replaceable energy dissipators was large, the latter was about 35% and 32% higher than the former respectively, so further research on the theoretical strength prediction model is needed to improve its prediction accuracy. The research results can provide reference for the seismic design of the flexural-shear energy dissipators.
