8.14.1. Types of Damping in Structures

Try these first

1. 1.

   Define viscous damping.

   Hint

   Think about how speed relates to the force.

2. 2.

   What is Coulomb damping caused by?

   Hint

   Consider the force opposing motion.

3. 3.

   What type of damping is proportional to velocity?

   • Coulomb Damping
   • Hysteretic Damping
   • Viscous Damping

   Hint

   Think about how speed plays a role in this type of damping.

4. 4.

   Coulomb damping is characterized by which of the following?

   • True
   • False

   Hint

   What does friction usually imply?

5. 5.

   A structure experiences harsh vibrations due to wind loads. Identify which type of damping would be most effective to mitigate these vibrations and justify your selection.

   Hint

   Consider how structures interact with wind forces.

6. 6.

   How would you analyze the effect of hysteretic damping in a material subjected to cyclic loading? Outline the steps and considerations in your method.

   Hint

   Think about material behavior during loading cycles.
