26.10.2. Layered Soil Profiles

Try these first

1. 1.

   What happens when a soft soil layer is between two hard layers?

   Hint

   Think about how waves travel through different materials.

2. 2.

   Define resonance in the context of construction and earthquakes.

   Hint

   It can lead to increased building movement.

3. 3.

   What effect does a soft layer between stiff layers have on seismic waves?

   • Trapping
   • No effect
   • Dissipation

   Hint

   Think about the movement of waves through different materials.

4. 4.

   True or False: Resonance only occurs in soft soils.

   • True
   • False

   Hint

   Consider all soil types.

5. 5.

   Evaluate and propose solutions for a building located in a soft-soil area at risk of wave amplification from layered profiles. Include design recommendations.

   Hint

   Think about how designs change with understanding the environment.

6. 6.

   Conduct an analysis of how Rayleigh waves behave when encountering a layered soil profile, emphasizing the role of dispersion in tall structures.

   Hint

   Look into how longer waves might relate to different structures.
