- 1.
What effect does higher damping have on spectral acceleration?
Hint
Think about how damping absorbs energy.
- 2.
Calculate the spectral acceleration for a building with a damping ratio of 10% if S_a,5% is 1.5 m/s².
Hint
Use the damping correction factor from the table.
- 3.
What happens to spectral acceleration as the damping ratio increases?
- It increases
- It decreases
- It stays the same
- Not enough information
Hint
Remember the relationship between damping and force absorption.
- 4.
True or False: A damping ratio above 30% is standard for most buildings.
- True
- False
Hint
No hint provided
- 5.
A new skyscraper is being designed in a high seismic zone. If the expected damping ratio is 25%, calculate the adjusted spectral acceleration if the raw S_a,5% value is 2.0 m/s².
Hint
Use the given damping ratio to apply the reduction factor.
