32.13.3. Foundation Types and their Seismic Behavior

Try these first

1. 1.

   What type of foundation is built to support single columns?

   Hint

   Think about small support structures.

2. 2.

   What is the primary benefit of mat foundations?

   Hint

   Consider how widely they spread the load.

3. 3.

   What is the primary characteristic of isolated footings?

   • They support multiple columns.
   • They support single columns.
   • They are always made of steel.

   Hint

   Consider what kind of structures use footings.

4. 4.

   True or False: Mat foundations are always shallow.

   • True
   • False

   Hint

   Think about their purpose and design.

5. 5.

   Design a scenario where an isolated footing might fail during an earthquake and propose mitigation strategies.

   Hint

   Consider soil strength and loading conditions.

6. 6.

   Evaluate the performance of mat foundations in a liquefaction zone and suggest solutions for stability.

   Hint

   Consider the effects of liquefaction on stability.
