Product introduction
It mainly includes the middle steel plate, the two outer steel plates and the friction material between the steel plates.
Product features
Friction is generated by the relative slippage between the middle steel plate and the friction material, which converts the vibration energy of the building into heat energy, thereby achieving the purpose of reducing the vibration response of the structure.
The hysteresis curve is basically rectangular, with obvious shock absorption effect; the velocity correlation and displacement correlation are small, and the performance is stable; the cycle durability is good and no later maintenance is required; the damping force can also be generated under small displacements; it will not be affected by major earthquakes It is damaged, so it does not need to be replaced; the mechanical model is simple, and the structural vibration reduction analysis and design are simple and easy; the structure is simple and the cost is low.
