21.16. Faults and Soil-Structure Interaction

Try these first

1. 1.

   What is Soft Soil Amplification?

   Hint

   Think about how soil types affect vibrational energy.

2. 2.

   Define differential movement.

   Hint

   Consider what happens to a bridge over a fault line.

3. 3.

   What happens to seismic waves when they pass through soft soils?

   • Weakens
   • Amplifies
   • Remains the same

   Hint

   Think about how softer materials react compared to harder ones.

4. 4.

   True or False: Differential movement can lead to structural failure.

   • True
   • False

   Hint

   Consider the implications of structures located on fault lines.

5. 5.

   Design a small building in a soft soil area considering fault-induced effects. Discuss the design choices you would make to mitigate seismic risks.

   Hint

   Reflect on the principles of soft soil amplification.

6. 6.

   Evaluate a proposed bridge plan that spans an active fault line. Identify potential issues due to differential movement and suggest solutions.

   Hint

   Think about how movement across fault lines would affect connectivity.
