Challenge Problems
Push your limits with advanced challenges
A building experiences vibrations due to nearby road traffic. Calculate the anticipated response if the natural frequency of the building is 2 Hz and the traffic generates a frequency of 2 Hz.
💡 Hint: Review resonance conditions.
Design a hypothetical building avoiding resonance by changing its natural frequency. If the original is 1.8 Hz, what parameters (mass or stiffness) would you alter?
💡 Hint: Think about how constructing taller columns could achieve this.
