Self-centering energy dissipation rocking frame is reconstructed from the initial RC frame by replacing the common column with the self-centering energy dissipation rocking column（SCEDRC）.The finite element model of each structure was established by finite element software OpenSees and dynamic elasto-plastic time history analysis was conducted in this paper.The seismic performance of the self-centering energy dissipating rocking frame was compared with that of the RC frame.The impact of installation angles

design parameters and positions on the seismic performance of the self-centering energy dissipation brace（SCEDB）were investigated.The results show that the seismic performance of the self-centering energy dissipation rocking frame is better than that of the RC frame.It aims to improve the deformation mode and reduce the damage and residual deformation of the structure.The variation of parameters has remarkable influence on the structural performance.When the SCEDB installation angle ranges from 30 degree to 40 degree

the seismic performance of the structure is the best.Increasing the first stiffness K1

second stiffness K2

initial pre-tensile stress P0 and friction force Fof SCEDB is beneficial to the seismic performance of the structure.When SCEDRC serves as the middle column

the overall seismic performance of the structure is the best.
