The invention relates to a recoverable steel structure technology which is used for solving the problems that a support in a central support steel frame is easy to yield, poor in anti-seismic property, large in residual deformation and weak in self-resetting capability, in particular to a central support steel frame device with a self-resetting double-limb shearing type energy consumption section. According to the center supporting steel frame device with the self-resetting double-limb shearing type energy dissipation section, the steel support, the double-limb shearing type energy dissipation section, the SMA bars and the belleville springs are used in cooperation, it can be effectively guaranteed that all components in the center supporting steel frame are stably connected, and after the support transmits axial force to the double-limb shearing type energy dissipation section under the earthquake effect, the energy dissipation section can be stably connected; shear yield is generated, and the input earthqua
