Abstract
A vibration energy absorber device includes a first fixing member fixed to a building bottom wall, a second fixing member fixed to a building foundation, a lead elastoplastic member having elasticity, both ends of the elastoplastic member being firmly coupled to the corresponding fixing members, and reinforcing members embedded in the elastoplastic member. The reinforcing members include a plurality of first members of a metal (e.g., iron) having a higher tensile strength than that of the elastoplastic member. The first members are wire rods extending from one end to the other end of the elastoplatic member, and are disposed in the elastoplastic member at equal angular intervals.
