3.2. Types of Damping

Try these first

1. 1.

   What is viscous damping?

   Hint

   Think about how some dampers work.

2. 2.

   Give an example of Coulomb damping.

   Hint

   Consider friction between surfaces.

3. 3.

   What is the primary characteristic of viscous damping?

   • Forces are constant
   • Forces are proportional to velocity
   • No forces involved

   Hint

   Think about how different dampers respond to movement.

4. 4.

   True or False: Coulomb damping is nonlinear.

   • True
   • False

   Hint

   Consider the constancy of friction.

5. 5.

   Design a simple model for a structure using composite damping mechanisms. Discuss how you would calculate the overall damping effect.

   Hint

   Think about how components interact in practice and their combined effects.

6. 6.

   Evaluate the significance of structural damping in high-rise building performance during a seismic event. What might happen without it?

   Hint

   Consider the role of internal material resistance as loads change.
