Challenge Problems
Push your limits with challenges.
Question 1
A structure has a natural frequency of 2 Hz, while an expected seismic event has dominant frequencies around 1.5 Hz. What are potential design modifications to mitigate resonance?
💡 Hint: Consider how adjustments to mass or stiffness can shift the natural frequency.
Question 2
Evaluate the consequences of not addressing resonance in the design of high-rise buildings in earthquake-prone areas.
💡 Hint: Reflect upon the historical instances where buildings failed due to resonance.
