Experimental and Numerical Study of Energy Dissipation Components of a New Metallic Damper Device

Abstract Purpose The novel metallic damper device for passive vibration control of structures, which is designed primarily seismic protection buildings, described in this paper. It consists the base plate, fixed into foundation, with two concentric cycles vertical components and a middle steel activating plate anchored to isolated structure. During an earthquake, moves together main structure causing bending components. Seismic energy absorbed due plastic deformation damper. performance various components, key elements studied advantages type reflect its ability adapt own features depending on intensity earthquake that it has equivalent characteristics every horizontal direction rotational symmetry. Methods Sixteen experimental tests damper, were conducted obtain their hysteretic behaviour. Numerical models using finite element method Abaqus/Standard software developed, validated verified experimentally obtained results. Results results show significant absorption can be used further research instead expensive tests. Conclusions possess extraordinary performance. If dissipation are properly maximum displacements, not expected suffer heavy damage or total failure during earthquakes.
