The utility model relates to an energy dissipation and vibration reduction supporting device, comprising a steel frame (1), a support body (2) and a damper (3); the steel frame (1) and the frame structure of the building are connected into a whole; the damper (3) is provided with two heads, one head is fixedly connected with the steel frame (1), the support body (2) is connected between the steel frame (1) and the other head of the damper (3). When the earthquake happens, the energy dissipation and vibration reduction supporting device can absorb and dissipate the input energy of the earthquake to enable the structure to stay in elastic state under the small earthquake effect; the demeanor, the intensity and the comfort degree of the structure can meet the normal serviceability requirement; under the strong earthquake effect, the earthquake response of the main structure is reduced by the energy dissipation and vibration reduction effect of the damper, the original structure is protected, and the vibration is reduced. By adopting the utility model, the features of the original building are protected, the architectural function requirements are also met.
