Challenge Problems
Push your limits with challenges.
Question 1
A structure with a natural frequency of 2 Hz is subjected to ground motion with a predominant frequency of 2 Hz. Describe the behavior of the structure and possible outcomes.
💡 Hint: Think about what happens in resonance when frequencies match.
Question 2
If an engineer wants to lower a building's natural frequency from 3 Hz to 1.5 Hz, what changes in design could they implement?
💡 Hint: Consider how the natural frequency is affected by mass and stiffness.
