33.2.2. Normalization

Try these first

1. 1.

   What does normalization in response spectra refer to?

   Hint

   Think about what 'normalizing' means in a general context.

2. 2.

   List one parameter used for normalization.

   Hint

   Recall some basic ground motion metrics.

3. 3.

   What is normalization of response spectra?

   • Adjusting data to a common reference
   • Ignoring peak ground parameters
   • Changing the frequency of the spectra

   Hint

   Think about why we want to have a consistent reference.

4. 4.

   True or False: Peak Ground Velocity (PGV) is not used in normalizing response spectra.

   • True
   • False

   Hint

   Recall the parameters we discussed.

5. 5.

   Consider a seismic zone where the average PGA is 1.5g. Determine how you would normalize a response spectrum based on this measurement.

   Hint

   Consider how you would factor in this ground acceleration into spectrum data.

6. 6.

   Evaluate the impacts of ignoring normalization on the response spectrum for a historical building in a high-PGA area.

   Hint

   Think about the repercussions of utilizing unrefined data in crucial designs.
