Supporting structure with damper independently adjusting rigidity and bearing capacity and design method thereof

The invention relates to a supporting structure with a damper independently adjusting the rigidity and the bearing capacity and a design method thereof. The supporting structure comprises a supportingsection, a damper section and a connecting end plate for being connected with the supporting section and the damper section, wherein the damper section is assembled by a plurality of connected damping plates side by side, and the damping plates are manually buckled. Compared with the prior art, the coupling aim of the traditional supporting rigidity and bearing capacity is achieved, and the aimsof controlling the yield timing sequence and achieving damage control design in the structure are achieved; modularized joint design is adopted, and a supporting system with the large rigidity-and-bearing-capacity variation range can be assembled through the damping plates with few types; the damper section is connected with the supporting section in series, yield/buckling damage of common rigidity supporting connected wit
