Question 1
What characterizes narrow-band ground motions?
- High energy spread over many frequencies
- High energy concentrated in a limited frequency range
- Energy distributed with no specific pattern
💡 Hint: Think about how energy distribution affects risk.
Question 2
True or False: Broad-band motions can lead to resonance.
- True
- False
💡 Hint: Consider the definition of resonance.

Challenge Problems
Push your limits with challenges.
Question 1
Calculate the risk of resonance for a building with a natural frequency of 2 Hz subjected to a narrow-band motion at the same frequency. What design considerations would you suggest?
💡 Hint: Consider what changes could reduce the likelihood of resonance.
Question 2
Describe how an earthquake with both narrow-band and broad-band characteristics would affect a high-rise building. What approaches can mitigate these effects?
💡 Hint: Think about the strategies you learned for handling varied motions.
