30.9. Limitations of Spectral Acceleration

Try these first

1. 1.

   What does the acronym SDOF stand for?

   Hint

   Think about how many directions the system moves.

2. 2.

   Why is linear elastic behavior an assumption in spectral acceleration?

   Hint

   Focus on what happens after the forces are removed.

3. 3.

   What does Sa assume about structural behavior?

   • A. Inelastic behavior
   • B. Linear elastic behavior
   • C. Plastic behavior

   Hint

   Focus on the basic assumptions made during Sa calculations.

4. 4.

   True or False: General code spectra can sometimes be fully generalized for all locations without adjustments.

   • True
   • False

   Hint

   Consider why site analysis is important.

5. 5.

   Analyze a scenario where a building's design utilizes spectral acceleration without considering inelastic behavior. What could be the potential risks?

   Hint

   Consider how forces exerted during an earthquake might differ from early theoretical expectations.

6. 6.

   Propose a detailed plan for conducting a site-specific seismic analysis for a new hospital. What steps should be included?

   Hint

   Think about why a one-size-fits-all approach does not work for complex structures.
