A staged damper combining friction energy dissipation and metal yielding. Based on displacement threshold control, it automatically switches energy-dissipation modes for different load and displacement conditions.
When damper displacement is below the staged threshold, only friction energy dissipation works. When displacement exceeds the threshold, friction and metal yielding work together.


DMSD adapts to different seismic levels and vibration conditions, providing staged energy dissipation, durability, flexible layout, and reduced damper quantity.
