Challenge Problems
Push your limits with challenges.
Question 1
Design a scenario for a multi-story building in a seismic zone. Outline how you would utilize mass alteration and dampers to avoid resonance.
💡 Hint: Think about how uneven weight distribution in a tall building can influence its stability.
Question 2
Given a building has a natural frequency in the range of 2 Hz, what design changes could you recommend to ensure it avoids resonance with an earthquake recording a frequency of 2 Hz?
💡 Hint: Raising frequency requires strengthening the structure.
