34.12. Influence of Soil-Structure Interaction (SSI)

Try these first

1. 1.

   What is Soil-Structure Interaction (SSI)?

   Hint

   Think about how buildings interact with the ground during an earthquake.

2. 2.

   What is base shear?

   Hint

   Consider the forces acting against a building due to shaking.

3. 3.

   What does Soil-Structure Interaction influence?

   • Natural Frequency
   • Base Shear
   • Damping
   • All of the Above

   Hint

   Consider the effects of ground movement on a building.

4. 4.

   True or False: Stiff soils increase structural amplification during an earthquake.

   • True
   • False

   Hint

   Think about soft versus hard soils.

5. 5.

   Design a small structure that is intended to be built on a soft soil site. Outline the design choices you would make to accommodate for SSI.

   Hint

   Think about how flexibility can help mitigate forces.

6. 6.

   Assess the repercussions of neglecting the potential impact of SSI when designing a high-rise building.

   Hint

   Consider real-world failures.
