2.2.3. Types of Damping Models

Try these first

1. 1.

   What is viscous damping?

   Hint

   Think about how quickly something moves.

2. 2.

   What causes Coulomb damping?

   Hint

   Consider surfaces rubbing against each other.

3. 3.

   What is the primary characteristic of viscous damping?

   • Constant force
   • Proportional to velocity
   • Forces due to mass only

   Hint

   Think about how it changes with speed.

4. 4.

   Coulomb damping is primarily caused by:

   • True
   • False

   Hint

   Consider surfaces under pressure.

5. 5.

   Explain how hysteretic damping could change the design approach for a new high-rise building in an earthquake-prone area.

   Hint

   Consider materials and how they respond during stress.

6. 6.

   If a structure experiences oscillations with a peak velocity of 10 m/s, and the damping coefficient is 200 Ns/m, calculate the damping force.

   Hint

   Use the viscous damping formula.
