27.9. Selection of Ground Motion Records

Try these first

1. 1.

   What is one criterion for selecting ground motion records?

   Hint

   Think about factors affecting seismic energy.

2. 2.

   What does soil condition refer to?

   Hint

   Consider how different soils might behave during an earthquake.

3. 3.

   What is one criterion for selecting ground motion records?

   • Soil density
   • Magnitude
   • Wind speed

   Hint

   Consider how energy influences the overall impact.

4. 4.

   True or False: Spectral compatibility ensures that ground motions match the expected response across frequencies.

   • True
   • False

   Hint

   Reflect on how records need to align with expected structural behavior.

5. 5.

   Consider a site located 10 km from a major fault zone. What factors should you analyze when selecting appropriate ground motion records?

   Hint

   Think broadly about what influences seismic waves as they travel.

6. 6.

   You are tasked with performing a seismic hazard analysis. How do you select and scale ground motion records for a new building on a clay soil site?

   Hint

   Consider how the building's resilience might change based on the clay soil.
