36.4.1. One-Dimensional Site Response Analysis

Try these first

1. 1.

   What is the main assumption of one-dimensional site response analysis?

   Hint

   Think about how layers are arranged in the soil.

2. 2.

   Name one software tool used for site response analysis.

   Hint

   Recap from our discussion on software.

3. 3.

   What major assumption is made in one-dimensional site response analysis?

   • The soil layers are vertical
   • The soil layers are horizontal
   • Soil layers have variable slopes

   Hint

   Think about how the soil is structured.

4. 4.

   SHAKE2000 is primarily used for:

   • True
   • False

   Hint

   Reflect on the software discussion.

5. 5.

   A site has three layers of soil with varying stiffness. If the input motion at bedrock yields 0.5g acceleration, how would this transform at the surface considering the soil types?

   Hint

   Review the soil properties and their relevance.

6. 6.

   Evaluate how changing soil properties from stiff to soft would affect the site response analysis results. What theoretical outcomes would you expect?

   Hint

   Think about how soft soils behave during seismic events.
