33.6.2. Features of Design Spectra

Try these first

1. 1.

   What defines a design spectrum?

   Hint

   Think about how structures must adapt to earthquake forces.

2. 2.

   Why is soil type important when discussing design spectra?

   Hint

   Consider how seismic waves interact with the ground.

3. 3.

   What are design spectra primarily used for?

   • To specify building materials
   • To assess structural responses to seismic events
   • To determine property values

   Hint

   Think about their role in planning for earthquake safety.

4. 4.

   True or False: Design spectra are the same for all soil types.

   • True
   • False

   Hint

   Consider how earthquakes affect different ground materials.

5. 5.

   Design a hypothetical building in a region classified as soft soil. What features should the design spectra incorporate based on the soil's properties?

   Hint

   Consider how soft soil interacts with seismic waves differently than rock.

6. 6.

   Evaluate the role of zoning in seismic design. How might improper zoning affect the safety of structures during an earthquake?

   Hint

   Think of zoning as a guide for safety standards.
