ABSTRACT A novel self-centering braced double-column rocking bent (SBRB) consisting of a double-column rocking bent and traditional or self-centering energy dissipation braces is developed analytically and numerically to enhance the seismic resilience. The analytical model of the SBRB is established, and numerical models of the SBRB are built to evaluate its seismic performance. Numerical results indicate that the SBRB is featured by prominent seismic performance including high lateral stiffness and strength, stable energy dissipation ability and good self-centering capability. The parameters of braces, axial force ratio, tendon prestress, and confinement play significant roles in the seismic responses of SBRB.
