Abstract: Self-centering energy dissipation brace (SCEDB) is widely used in braced frame structures due to its superior energy dissipation and self-centering ability. On the basis of previous research, a rotating self- centering energy dissipating brace (RSC-EDB) was proposed by taking the advantage of the large deformation and strong resetting ability of volute springs, as well as of the stable energy dissipation of lead. The constructional form and working mechanism were clarified and the restoring force model of RSC-EDB was established. The influences of prestressing, of constitutive parameters of vortex springs, of lead shear surface area, of reset ratio α_sc, and of energy dissipation factor β on the braced hysteretic performance were analyzed using finite element software. The seismic behavior of frame structures with different bracing arrangement forms was investigated. The study results show that: The mechanical properties of RSC-EDB can be accurately predicted by the established restoring force model of RSC-EDB; The energy dissipation capacity and reset capacity can be better satisfied when α_sc is 0.95~1.1 and β is 1; The seismic behavior of the RSC-EDB frame structure is significantly improved compared to the pure steel frame, with the form of cross-storey X-bracing arrangement having the best impact on the control of inter-storey displacement angle.
