Question 1
What is Peak Ground Acceleration (PGA)?
- The maximum ground velocity.
- The maximum ground acceleration.
- The minimum vertical acceleration.
💡 Hint: Focus on the term 'maximum'.
Question 2
True or False: Floor accelerations can be lower than PGA.
- True
- False
💡 Hint: Consider the effect of resonance.

Challenge Problems
Push your limits with challenges.
Question 1
Given a building with a height of 30 meters during an earthquake where PGA is recorded at 0.25g, estimate the potential floor acceleration at the roof level, considering resonance may increase it by 3 times.
💡 Hint: Use the rule of tripling for floors above ground in seismic scenarios.
Question 2
Discuss how a building’s design might change if the PGA is higher than anticipated and how this affects planning for non-structural systems.
💡 Hint: Relate back to the reactions of buildings during major earthquakes.
