6.13. Effect of Damping on Seismic Response

Try these first

1. 1.

   What is damping?

   Hint

   Think about how shaking can be lessened in a structure.

2. 2.

   List two types of damping.

   Hint

   Consider different energy dissipation mechanisms.

3. 3.

   What is the primary benefit of damping in earthquake engineering?

   • Increase building height
   • Reduce amplitude of oscillations
   • Add aesthetic value
   • Increase base shear

   Hint

   Think about the motion of a building during an earthquake.

4. 4.

   True or False: Hysteretic damping occurs due to elastic deformation of materials.

   • True
   • False

   Hint

   Consider how materials behave under stress.

5. 5.

   Given a building with a damping ratio of 5% and subjected to an earthquake, discuss how increasing this ratio to 8% might alter its response.

   Hint

   Consider the relationship between damping and oscillation.

6. 6.

   Design an experiment using different materials to measure how hysteretic damping behaves under varying cyclic loading conditions.

   Hint

   Think about how changes in material will impact their hysteretic behavior.
