Abstract

In order to investigate the effect of opening radius and different ways to change the cross-sectional area on the energy dissipation capacity of a single-circle hole mild steel damper, this paper changes the hole diameter by increasing the inner and outer diameters, keeping the radius difference unchanged, and expands the cross-sectional area of the damper by increasing the thickness, enlarging the outer diameter, and decreasing the inner diameter, and a total of 3 groups and 12 models were established to analyze the hysteresis curve, skeleton curve, energy dissipation-displacement curve, stress distribution and related simulation results of the dampers to evaluate their energy dissipation capacity through the reciprocating displacement loading mode. The study shows that the energy dissipation performance of the damper gets worse as the inner diameters and outer diameters increase more, and that decreasing the inner diameter improves the energy dissipation capacity more than increasing the outer diameter over increasing the thickness.
