Question 1.
What does Power Spectral Density (PSD) represent?
Show hintHide hint
Focus on what PSD helps us understand in vibrations.
Question 2.
Name an application of PSD in earthquake engineering.
Show hintHide hint
Think about how engineers use statistical methods.
3Question 3.
What is Power Spectral Density (PSD)?
- A statistical analysis method
- An energy distribution measure over frequency
- A type of structural material
Show hintHide hint
Think about what power distribution means in this context.
4Question 4.
True or False: Narrow-band motions spread energy widely across many frequencies.
Show hintHide hint
Consider how energy can be concentrated.
Question 5.
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.
Show hintHide hint
Focus on the resonance effect when frequencies align.
Question 6.
Imagine a scenario where several vibrations from different earthquakes impact a structure. How would you use PSD analysis to decide on structural reinforcements?
Show hintHide hint
Think about the importance of frequency knowledge for design decisions.
