40.20.2. Damping Devices

Try these first

1. 1.

   What is the primary function of damping devices?

   Hint

   Think about what happens during an earthquake.

2. 2.

   Name one type of damping device.

   Hint

   Recall the examples discussed.

3. 3.

   What type of damping device absorbs energy with a fluid?

   • Tuned Mass Damper
   • Metallic Yield Damper
   • Viscous Damper

   Hint

   Remember the fluid-based mechanism.

4. 4.

   Tuned mass dampers are designed to counteract specific:

   • Oscillations
   • Earthquake forces
   • Dead loads

   Hint

   Think about the tuning aspect.

5. 5.

   Design a small building that incorporates both a viscous damper and a tuned mass damper. Explain how each device contributes to the overall earthquake resistance of the structure.

   Hint

   Think about how each device reacts differently to forces.

6. 6.

   Analyze a failed building in an earthquake and propose a hypothetical damping device system that could have prevented damage. What types would you use and why?

   Hint

   Consider both energy absorption and permanence of deformation in your design.
