Technical Field

[0001] The utility model relates to the technical field of dampers, in particular to a polymerized yield damper. Background Art

[0002] Today's buildings tend to be taller and taller. Frame structures composed of steel components, composite components or reinforced concrete components are often used in buildings. In order to make the building structure have a strong ability to resist damage from external forces such as earthquakes and wind loads, it is often necessary to add various energy-absorbing devices to the frame structure. Shear-type metal yield dampers are widely used in engineering due to their good economy and superior mechanical properties. Existing dampers first consume energy through wing plates when consuming energy, and then consume energy through energy-absorbing plates after the yield force reaches a certain level. When the performance requirements of buildings are high, the existing dampers cannot better meet the energy consumption requirements. For example, the existing dampers have low energy consumption. When the dampers are subjected to strong shear pressure, the dampers are prone to buckling, which causes the wall to bend easily or bulge inside the wall, reducing the service life of the wall. Therefore, a polymerized yield damper is provided to solve the problems raised in the above background technology. Utility Model Content
