36.2.2. Ground Motion Selection

Try these first

1. 1.

   What is ground motion selection?

   Hint

   Think about how we may want to understand the impact of earthquakes.

2. 2.

   Name one criterion for selecting ground motions.

   Hint

   Consider aspects that might impact building responses.

3. 3.

   What is the main purpose of ground motion selection?

   • To increase design costs
   • To match expected seismic behavior
   • To simplify analysis

   Hint

   Think about why we analyze earthquakes in the first place.

4. 4.

   True or False: The site classification affects the selection of ground motions.

   • True
   • False

   Hint

   Consider the impact of different soil types on shaking.

5. 5.

   You are tasked with selecting ground motions for a new high-rise building in a soft soil area within a major seismic zone. Outline the steps and criteria you would use in this selection process, including how you address the site-specific conditions.

   Hint

   Consider how the characteristics of the seismic source will impact the building.

6. 6.

   Critique the possible risks associated with only relying on generic ground motion data instead of site-specific data for a critical infrastructure project.

   Hint

   Think about how different quakes can act differently based on geological context.
