Question 1.
What is the damping ratio (ξ)?
Show hintHide hint
Think of energy dissipation in cycles.
Question 2.
List typical damping ratios for dry sand and soft clay.
Show hintHide hint
Recall the values discussed in class.
3Question 3.
What is the range of damping ratios for saturated sand?
- 1–2%
- 2–5%
- Up to 10%
Show hintHide hint
Consider the variability of soil types.
4Question 4.
True or False: A higher damping ratio indicates a higher risk of liquefaction.
- True
- False
Show hintHide hint
Remember what we learned about energy dissipation.
Question 5.
Given a soil sample with varying damping ratios, how would you assess its potential for liquefaction during a seismic event? Include factors that affect the damping ratio in your answer.
Show hintHide hint
Think about how damping affects liquefaction risk.
Question 6.
If a construction site has dry sand and saturated clay, how should you approach foundation design considering their different damping ratios?
Show hintHide hint
Compare the characteristics of both soil types.
