38.5.6. Structural Redundancy

Try these first

1. 1.

   What is structural redundancy?

   Hint

   Think about how loads are distributed in buildings.

2. 2.

   How does redundancy relate to ductility?

   Hint

   Consider what happens when one part of a structure fails.

3. 3.

   What does structural redundancy primarily improve in a structure?

   • Cost
   • Aesthetics
   • Safety
   • Durability

   Hint

   Think about what a backup does.

4. 4.

   Does higher ductility mean a material can handle sudden loads better?

   • True
   • False

   Hint

   Consider the flexibility of the material.

5. 5.

   Design a small structure incorporating at least three forms of redundancy. Explain how each contributes to safety.

   Hint

   Think creatively about what kinds of structural features can work together.

6. 6.

   Evaluate the structural design of a building that experienced significant earthquake damage. What modifications would you suggest to improve redundancy?

   Hint

   Research the building and its original design limitations.
