Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What is the formula used to calculate Spectral Acceleration?
- Sa(T
- ζ) = max |x¨(t)|
- Sa = PGA x T
- Sa = g x ζ
💡 Hint: Focus on the elements involved in the seismic response.
Question 2
True or False: Spectral Acceleration can be derived solely from numerical simulations.
- True
- False
💡 Hint: Think about the different methods we've discussed.

Challenge Problems
Push your limits with challenges.
Question 1
Given a time history of ground motion data, apply the Newmark-beta method to calculate the Spectral Acceleration for specific periods ranging from 0.5s to 2.0s, analyzing how changes in damping ratios impact the results.
💡 Hint: Break down into smaller time increments for clarity when using numerical methods.
Question 2
Evaluate how the soil type (soft, medium, hard) influences the calculated Sa by comparing two SDOF systems subjected to identical ground motions but differing soil characteristics.
💡 Hint: Consider the properties of each soil type and how they interact with seismic energy.
