33.8. Site Effects and Soil Amplification

Try these first

1. 1.

   What does it mean for soil to amplify seismic waves?

   Hint

   Consider the comparison between solid rock and clay soil.

2. 2.

   Name one type of soil according to the IS code classification.

   Hint

   Think about the hardest soil category.

3. 3.

   What is meant by soil amplification?

   • Decrease in wave intensity
   • Increase in wave intensity
   • No effect

   Hint

   Think about how softer soil reacts to seismic waves compared to hard soil.

4. 4.

   True or False: The IS code provides different spectra shapes for various soil types.

   • True
   • False

   Hint

   Consider the role of building codes in structural safety.

5. 5.

   A city wants to build a new hospital in a soft soil area. Discuss the considerations engineers must make regarding seismic design and the implications of using standard design spectra versus site-specific versions.

   Hint

   Reflect on the differences in building standards for various soil types.

6. 6.

   Evaluate the impact of ignoring soil conditions when designing infrastructure in an earthquake-prone area. What could be the potential consequences?

   Hint

   Think about historical earthquake disasters and their links to construction practices.
