Challenge Problems
Push your limits with advanced challenges
You are assigned to evaluate an old building's structural integrity in an earthquake-prone area. Discuss the steps you would take using modal testing and how you would apply FFT in the analysis.
💡 Hint: Think about why it’s crucial to address how the building reacts to vibrations.
Design a mini-project where you can measure the vibrations of a specific structure in your locality. Outline the steps to use modal testing and how you'd interpret the results.
💡 Hint: Consider local buildings and how their designs might be affected by their vibrational behavior.
