36.11.1. Selection Criteria

Try these first

1. 1.

   What is the importance of selecting ground motions in seismic analysis?

   Hint

   Think about what happens if we don’t choose correctly.

2. 2.

   Name one factor that should be considered in ground motion selection.

   Hint

   Consider the elements that affect ground shaking.

3. 3.

   Why is it important to match the magnitude of selected ground motions with the target design spectrum?

   • To ensure accurate risk assessment
   • To make the design more conservative
   • None of the above

   Hint

   Think about the potential failure of underestimating the seismic forces.

4. 4.

   True or False: Site conditions do not significantly influence ground motion characteristics.

   • True
   • False

   Hint

   Consider how different types of ground can change the shaking experience.

5. 5.

   You have a building designed for a seismic event of magnitude 7.0 on a thrust fault. Explain how you would select appropriate ground motions.

   Hint

   Consider the characteristics of your design earthquake.

6. 6.

   A site has a soft soil profile. Describe how this affects your ground motion selection process.

   Hint

   Remember the influence of ground type on how seismic waves behave.
