Challenge Problems

Push your limits with challenges.

Question 1

A bridge has a damping coefficient of 15 Ns/m, stiffness of 5000 N/m, and mass of 1200 kg. Calculate the equivalent damping ratio. Discuss how this impacts the bridge's design against earthquakes.

💡 Hint: Make sure to plug in values correctly and assess how damping influences design choices.

Question 2

Compare how structures with high equivalent damping ratios behave under dynamic loading versus those with low ratios. Provide examples of each type.

💡 Hint: Think through how energy is dissipated differently in these cases.
