Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What is the relationship between Peak Ground Acceleration and the forces acting on a structure?
- Higher PGA means less force
- Higher PGA results in larger forces
- PGA has no impact on forces
💡 Hint: Remember what happens when acceleration increases.
Question 2
True or False: Longer durations of ground motion do not affect structures.
- True
- False
💡 Hint: Think about how repeated stress can affect materials.

Challenge Problems
Push your limits with challenges.
Question 1
Given a building with a natural frequency of 2 Hz, determine the risks if predominant ground motion has a frequency of 2.2 Hz during an earthquake.
💡 Hint: Assess the proximity of the frequencies to understand the resonance impact.
Question 2
Calculate the potential inertia force experienced by a mass of 500kg with a Peak Ground Acceleration of 0.8g during an earthquake.
💡 Hint: Remember the formula for force: F = ma.
