33.9.1. Vertical Response Spectra

Try these first

1. 1.

   What is a vertical response spectrum?

   Hint

   Think about how it relates to horizontal spectra.

2. 2.

   Name one type of structure that must consider vertical motions.

   Hint

   Consider structures that extend vertically.

3. 3.

   What fraction of horizontal response spectra do vertical response spectra typically represent?

   • 1/4
   • 1/2
   • 2/3

   Hint

   Consider how different fractions represent vertical aspects.

4. 4.

   True or False: Vertical response spectra are irrelevant in the design of cantilevers.

   • True
   • False

   Hint

   Think about the structural characteristics of cantilevers.

5. 5.

   A bridge is designed to minimize vertical movements during seismic events. If the horizontal spectra reaches a peak of 0.5g, what would you expect the vertical response spectra to be?

   Hint

   Recall the ratios we discussed.

6. 6.

   Consider how the design of heavy equipment like cranes incorporates vertical response spectra. Describe how engineers analyze potential risks.

   Hint

   Think about the implications of vertical loading.
