Challenge Problems
Push your limits with advanced challenges
A multi-story building constructed with steel exhibits a low damping ratio of 2%. During a severe earthquake, how would this affect the building's response compared to a reinforced concrete building with a damping ratio of 5%?
💡 Hint: Consider how energy is dissipated in both materials.
Describe the potential consequences of neglecting to factor in damping during the design process of a high-rise structure in a seismic zone.
💡 Hint: Think about how vibrations amplify without adequate control.
