Challenge Problems
Push your limits with advanced challenges
A building has a natural period of 0.5 seconds. Discuss the implications of this period concerning maximum spectral acceleration in a seismic zone rated with high ground acceleration values.
💡 Hint: Think about how natural frequency relates to seismic forces.
Graph an Elastic Response Spectrum for a hypothetical structure with known maximum responses at multiple periods ranging from 0.1s to 2.0s. Discuss how the results inform design choices.
💡 Hint: Reflect on how you model structural responses in your graph.
