Question 1.
What does Spectral Acceleration (Sa) represent?
Show hintHide hint
Think about how structures respond to shaking.
Question 2.
Name one characteristic of Single Degree of Freedom (SDOF) systems.
Show hintHide hint
SDOF systems focus on one motion type.
3Question 3.
What does a response spectrum show?
- A snapshot of static forces
- How structures react to ground motion
- The weight of a building
Show hintHide hint
Focus on the purpose of the spectrum.
4Question 4.
True or False: Inelastic spectra assume that structures remain unchanged after a seismic event.
- True
- False
Show hintHide hint
Consider whether any damage can occur.
Question 5.
A 10-story building has been designed with an elastic spectrum in mind. During an earthquake, peak spectral acceleration recorded is 0.3g. If the building shifts to an inelastic response and undergoes damage, describe the implications for future design improvements.
Show hintHide hint
Think about how damage would affect structural integrity.
Question 6.
An engineer needs to evaluate whether a building should be retrofitted based on its inelastic spectrum response. The building shows a displacement limit of 0.05m but has experienced greater during an event. What actions should the engineer take?
Show hintHide hint
Focus on how the response spectrum informs design decisions.
