Damping type tension and compression damper

The utility model relates to a damping type tension and compression damper, which belongs to the technical field of structural vibration control and comprises assembly plates, an energy dissipation main steel plate is fixed between the assembly plates, an energy dissipation auxiliary steel plate is arranged between the assembly plates, the energy dissipation auxiliary steel plate is positioned in the direction of the inner side of the energy dissipation main steel plate, and connecting pieces are fixed at the upper end and the lower end of the energy dissipation auxiliary steel plate. And the connecting piece is fixedly connected with the assembling plate. The utility model has the beneficial effects that the arc-shaped main steel plate between the assembly plates can be stressed to deform in the process of amplitude generation of a building, so as to absorb and counteract vibration force, and meanwhile, the energy-consuming auxiliary steel plate can bend outwards to deform in the same way, so that the energy
