ENERGY DISSIPATION DAMPER BASED ON TENSION AND COMPRESSION YIELD OF PERFORATED STEEL PLATE

WIPO Patent Application WO/2021/057092

A1

The present invention relates to an energy dissipation damper based on tension and compression yield of a perforated steel plate, which belongs to the field of buildings. An energy dissipation damper based on tension and compression yield of a perforated steel plate, comprising a perforated core plate, outer restraining plates and cone-shaped connecting members; the perforated core plate is provided with first connecting holes and second connecting holes for connecting the cone-shaped connecting members, and third connecting holes for connecting the outer restraining plates; the cone-shaped connecting members are located at upper and lower ends of the perforated core plate, the outer restraining plates are located at two sides of the central part of the perforated core plate, and the cone-shaped connecting members and the outer restraining plates can slide relative to each other on the perforated core plate. The present invention provides a new energy dissipation apparatus for improving the anti-seismic performance of structural members such as columns and piers; in addition, the present invention has a simple structure and is easy to assemble, being suitable for prefabricated buildings.
