Challenge Problems

Push your limits with challenges.

Question 1

Consider a modern high-rise building designed with a fundamental natural frequency of 1 Hz. If an earthquake occurs producing a frequency of 1 Hz, what implications does this resonance have for the building's integrity?

💡 Hint: Think about how matching frequencies affect the energy transfer and overall stability.

Question 2

Evaluate the effectiveness of a hypothetical retrofitting method that involves adding additional mass to the rooftop of a building to lower its natural frequency. Discuss the pros and cons.

💡 Hint: Consider not just the intended effects but potential additional impacts on the structure.
