PROBLEM TO BE SOLVED: To provide a friction attenuation energy absorption device that can be used at buildings, bridges, large-sized objects or facility, can absorb, insulate three-dimensional vibration energy of earthquake and environment and prevent its operating temperature from being increased and can apply an automatic adjustment function about attenuation and rigidity.SOLUTION: A friction attenuation energy absorption device has at least one core column [10], two support plates [20], a plurality of first material layers [30] and a plurality of second material layers [40]. At least one core column has a plurality of sliding sheets [11] laminated to each other. The two support plates are fixed to two ends of at least one core column. The first material layer and the second material layer are alternatively fixed between the two support plates and enclose at least one core column, the first material layer and the second material layer are alternatively fixed by at least one sliding sheet of the core column.SELECTED DRAWING: Figure 2 |
