Question 1.
What does PGA stand for?
Show hintHide hint
Think about how ground shaking is measured.
Question 2.
How does epicentral distance affect PGA?
Show hintHide hint
Consider the energy loss over distance.
3Question 3.
What does PGA measure during an earthquake?
- Rotational forces
- Peak ground acceleration
- Vertical displacement
Show hintHide hint
Focus on the term 'peak' in relation to ground motion.
4Question 4.
True or False: PGA increases linearly with earthquake magnitude.
- True
- False
Show hintHide hint
Think about how energy release can vary.
Question 5.
Calculate the expected PGA for a given magnitude and distance using GMPE. Consider a magnitude 7 earthquake at a distance of 30 km.
Show hintHide hint
Remember to review the parameters used in GMPE.
Question 6.
Design a structural component that considers site conditions and fault type for safety. Describe the factors to consider and how they would affect your design.
Show hintHide hint
Think of how structures behave under different conditions.
