2 cards from this section. Quick, good the night before a test.
Define Elastic Response Spectrum.
Think about what a spectrum represents in terms of responses.
What does SDOF stand for?
Consider how many motion directions this type of model addresses.
What does the Elastic Response Spectrum represent?
Reflect on what we discussed regarding the behavior of structures under seismic conditions.
True or False: Spectral acceleration is independent of the damping ratio.
Consider how damping usually influences system responses during shaking.
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.
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.
Reflect on how you model structural responses in your graph.
