26.3. Rayleigh Waves

Try these first

1. 1.

   What type of motion do Rayleigh waves exhibit?

   Hint

   Think about how ocean waves move.

2. 2.

   Are Rayleigh waves surface waves or body waves?

   Hint

   Recall the basic classification of seismic waves.

3. 3.

   What type of motion do Rayleigh waves exhibit?

   • Transverse
   • Retrograde elliptical
   • Longitudinal

   Hint

   Think about how ocean waves roll.

4. 4.

   Are Rayleigh waves more destructive in soft soils?

   • True
   • False

   Hint

   Recall how materials affect wave propagation.

5. 5.

   You are tasked to evaluate a building's resilience against Rayleigh waves in a region with soft soil. What factors would you consider, and why?

   Hint

   Think about the interaction between soil properties and building design.

6. 6.

   Mathematically derive the effect of Poisson's ratio on Rayleigh wave velocity in a layered medium. Provide a clear explanation.

   Hint

   Relate the formula back to materials used in construction typically found in seismic analysis.
