8.14. Use of Damping in Controlling Harmonic Response

Try these first

1. 1.

   What is viscous damping?

   Hint

   Think about how friction affects moving objects.

2. 2.

   Define hysteretic damping.

   Hint

   Consider how materials behave under repetitive stress.

3. 3.

   What type of damping is proportional to velocity?

   • A. Coulomb Damping
   • B. Viscous Damping
   • C. Hysteretic Damping

   Hint

   Remember the relationship between force and motion.

4. 4.

   Coulomb damping is dependent on material properties. True or False?

   • True
   • False

   Hint

   Think about how it responds to the motion direction.

5. 5.

   Consider a structure designed with a low damping ratio. Explain the potential consequences during a seismic event.

   Hint

   Think about how energy accumulates without effective dissipation.

6. 6.

   Evaluate how introducing viscous dampers in a building can affect its natural frequency and dynamic response.

   Hint

   How does adding mass or dampers modify a system's frequency response?
