Question 1
What is Power Spectral Density (PSD)?
- A statistical analysis method
- An energy distribution measure over frequency
- A type of structural material
💡 Hint: Think about what power distribution means in this context.
Question 2
True or False: Narrow-band motions spread energy widely across many frequencies.
💡 Hint: Consider how energy can be concentrated.

Challenge Problems
Push your limits with challenges.
Question 1
Consider a building designed with a natural frequency of 2 Hz. Analyze how a narrow-band earthquake motion with a peak frequency of 2 Hz will affect the structure.
💡 Hint: Focus on the resonance effect when frequencies align.
Question 2
Imagine a scenario where several vibrations from different earthquakes impact a structure. How would you use PSD analysis to decide on structural reinforcements?
💡 Hint: Think about the importance of frequency knowledge for design decisions.
