Seven groups of self-centering energy dissipation brace models of arc steel plates with different configurations were established based on ABAQUS software. A method for calculating the internal forces, stiffness, yield displacement and yield load of a brace was derived and shows agreement with theoretical values. This brace shows a favorable hysteretic performance that corresponds to its full, flag-shaped hysteretic curve. The stiffness transition of various stages is smooth and stable. The maximum residual deformation of the component is 3.75mm and decreases as prepressing of the disc springs is increased. The component's reset performance can be fully utilized to satisfy specific needs. The advised values for designing the energy dissipation components of an arc steel plate are described as follows: 1/250 of a radian, width of 50–80mm and thickness of 20 mm. The damping force, damping displacement and brace stiffness of the SEDB can be adjusted by the structural parameters of the arc steel plate to satisfy the engineering requirements Workplace Institute of Theoretical and Applied Mechanics Contact Kulawiecová Kateřina, kulawiecova@itam.cas.cz, Tel.: 225 443 285 Year of Publishing 2020 Electronic address https://doi.org/10.1016/j.soildyn.2019.105751
