Challenge Problems
Push your limits with advanced challenges
Consider a high-rise building with a fundamental frequency of 1 Hz. If the second mode frequency is 1.5 Hz, discuss whether to use SRSS or CQC for seismic response calculations.
💡 Hint: Reflect on how close frequencies can influence modal interactions.
Evaluate how the Response Spectrum Method would change if a building’s damping ratio increases from 2% to 10%. Discuss the implications.
💡 Hint: Think about how damping influences seismic response calculations.
