Vibration energy absorber device

A vibration energy absorber device located between two construction members, having oppsite surfaces spaced apart from each other, for absorbing vibration energy causing a relative displacement of the construction members along a direction parallel thereto, comprising:

• first and second fixing members, respectively mounted on the construction members such that at least a displacement of each fixing member relative to the corresponding construction member along the parallel direction is prevented;
• an elastoplastic member which is located between the first and second fixing members, the elastoplastic member having two ends which are respectively coupled to the first and second fixing members and being subjected to plastic shear deformation;
• and
• reinforcing means embedded in the elastoplastic member so as to allow plastic shear deformation of the elastoplaetic member, the reinforcing means including a plurality of first reinforcing members made of a material having a higher mechanical strength than that of the elastoplastic member, and the first reinforcing members extending from one end to the other end of the elastoplastic member, and being distributed along a peripheral portion of the elastoplastic member.
