Effect.
The yield strength of the conical mild steel 3 is 235MPa.
The operation principle of the utility model is：
In earthquake, 1 stress of upper junction plate being connected to below building, using conical mild steel 3 occur curved drawing deformation,
The frictional force of stretcher strain and groove profile friction plate 4 and upper junction plate 1, the common earthquake energy of three occur for SMA silks 5；When
When big shake, by adjusting external voltage at any time, changes the pre-jacking force that piezoelectric pile 8 applies its groove profile friction plate 4, make groove profile friction plate
4 increase with 1 frictional force of upper junction plate, and the energy dissipation capacity of whole device is more abundant.After shake, SMA silks 5 utilize itself super-elasticity
Make its Self-resetting.
