Under small earthquakes, a steel framework and the wood shear walls work together, so that the structure is enabled to have higher lateral stiffness; under middle earthquakes or big earthquakes, a shear force applied to the friction type dampers is greater than a slip shear force of the friction type dampers, friction surfaces of the friction type dampers start to slip to consume energy, and the damage to the wood shear walls can be reduced to a large extent; the post-tensioned unbounded prestressed tendons are always in an elastic tension state, beam column nodes after an earthquake return to an initial state under the action of the post-tensioned unbounded prestressed tendons, the steel beams and the steel columns are basically not damaged, residual deformation of the structure is very small, and the friction type dampers are not damaged under the action of the earthquake and has no need to be replaced after the earthquake.

The invention relates to a nested U-shaped staged yield damper, and belongs to the technical field of structural engineering energy dissipation and shock absorption. The metal damper is composed of two U-shaped energy dissipation parts which are nested in the same direction in the horizontal direction, a double-layer corrugated energy dissipation part, a brass base plate and a steel cushion block.According to the nested U-shaped staged yield damper, the design concepts that staged yield is adopted, energy dissipation parts can be replaced, the shear bearing capacity of the damper is improved,out-of-plane buckling is restrained, the structural rigidity is improved, and various energy dissipation mechanisms work together and the like are applied, and the limitation of a traditional metal damper is broken through. Staged yield is achieved through the nesting design of the U-shaped energy dissipation parts and the arrangement of the steel cushion block. Meanwhile, the reasonably designeddamper has good shear bearing capacity and energy dissipation performance, the normal use function can be recovered only by replacing the energy dissipation parts after an earthquake, and the economic benefit is obvious. The metal damper develops towards the assembling direction, replacement is convenient, arrangement modes are various, and the number of the metal dampers can be flexibly increased or decreased according to actual conditions.
