[0028] Specifically, the arc-shaped base 1 and the plate-shaped base 4 can both be used as bases for the main support device 100 and the auxiliary support device 200.

[0029] Among them, the core material block 302 can be a metal core material, and the metal core material usually uses steel plates or steel pipes as the core material, which can provide higher yield strength and good ductility.

The core material block 302 can also be a shape memory alloy. Using shape memory alloy as the core material of BRB can utilize its recovery ability after being stressed. The core material block 302 can adopt a specially designed straight inner core or other shapes to provide better longitudinal constraints, reduce local buckling effects, and improve fatigue performance. In addition, the core material block 302 will add non-bonded materials outside the metal core material to provide additional energy dissipation capacity.
