Challenge Problems
Push your limits with advanced challenges
A building is designed with a natural frequency of 8 Hz and a damping ratio of 0.3. Calculate its damped natural frequency and discuss why this might be beneficial in an earthquake-prone area.
💡 Hint: Keep the damping ratio's impact in mind while calculating.
Discuss the implications of a high damping ratio versus a low damping ratio in building design. Which would provide better earthquake resistance and why?
💡 Hint: Consider how the modified response functions would impact structural behavior under dynamic loads.
