ABSTRACT:
An elasto-plastic damper is disclosed which comprises either a metal block-like or a metal plate-like damper body, each having a plurality of spaced apart openings extending therethrough to provide elastic deformability to the damper body. The elasto-plastic damper is adapted to connect bifurcated axially aligned structural members in a building. When an earthquake tremor impacts upon the building, the vibrational energy transmitted to the bifurcated axially aligned structural members is attenuated by the interconnecting elasto-plastic dampers.
