25.12.2. Implications for Foundation Design

Try these first

1. 1.

   What is the hypocentre?

   Hint

   Think about the starting point of an earthquake.

2. 2.

   Define site amplification factors.

   Hint

   Consider how waves behave differently in sand vs. rock.

3. 3.

   What does the hypocentre refer to?

   • Surface of the Earth
   • The point of initial rupture
   • Seismic waves' endpoint

   Hint

   Remember where an earthquake originates.

4. 4.

   True or False: Shallow hypocentres generally lead to stronger shaking.

   • True
   • False

   Hint

   Think about how close waves are to the ground.

5. 5.

   Develop a scenario where a city with varying soil types is hit by an earthquake originating from a shallow hypocentre. Assess the impact and suggest engineering safety measures.

   Hint

   Consider how soil affects wave intensity and amplification.

6. 6.

   A building designed on solid rock is re-evaluated after discovering it's on soft clay. Discuss the steps engineers should take to ensure the structure meets safety standards under potential seismic stresses.

   Hint

   Think about the structural adjustments needed for softer soils.
