Self-centering energy dissipation device and wall damping assembly

A self-centering energy dissipation device adapted to be connected to a first object and a second object, said self-centering energy dissipation device comprising:

• a first base seat adapted to be connected to the first object;
• at least one main shaft extending through said first base seat;
• two second base seats connected respectively and movably to two opposite ends of said at least one main shaft and adapted to be connected to the second object;
• and
• at least one pair of elastic members sleeved on said at least one main shaft, each of said at least one pair of elastic members having a first end abutting against said first base seat, and a second end abutting against a respective one of said second base seats, wherein said first base seat is substantially T-shaped, and includes
• an abutment wall permitting said at least one main shaft to extend therethrough, and
• a first attaching wall transverse to and connected to one side of said abutment wall.
