Question 1
Given a tower’s height of 100m, analyze how higher modes impact its seismic performance. Discuss design adaptations that could mitigate risks.
💡 Hint: Consider the principles of vibration and resonance.
Question 2
A dam has shown that its hydrodynamic effects worsen seismic forces during testing. Propose adjustments to its design based on modern engineering principles to reduce this effect.
💡 Hint: Think of ways to let the water and structure 'move' together.
