Challenge Problems
Push your limits with challenges.
Question 1
Given a building with modes contributing participation factors of 0.4, 0.6, and 0.8, calculate the total effective modal mass if the mass for these modes is 5000 kg.
💡 Hint: Sum the contributions of each mode using their participation factors.
Question 2
Discuss why analyzing only the fundamental mode might be insufficient for accurate seismic response modeling.
💡 Hint: Consider how higher modes interact with the fundamental mode.
