Challenge Problems
Push your limits with challenges.
Question 1
A 10-story building has a natural frequency of 1 Hz. During an earthquake, the ground motion has a frequency of 1 Hz. Analyze the effect of this resonance without sufficient damping.
💡 Hint: Think about how resonance changes the amplitude of vibrations.
Question 2
Propose an engineering solution to reduce the impact of resonance in a high-rise structure undergoing severe seismic loading.
💡 Hint: Consider how mass can be used to counteract movement.
