39.15. Seismic Retrofitting to Improve Ductility

Try these first

1. 1.

   What does retrofitting mean?

   Hint

   Think about the modifications made to old structures.

2. 2.

   Name one technique used in retrofitting.

   Hint

   Consider common methods to enhance structures' abilities.

3. 3.

   What is seismic retrofitting?

   • A method of constructing new buildings
   • Modifying existing structures to improve seismic performance
   • A type of architectural style

   Hint

   Think about how old buildings can be updated for safety.

4. 4.

   True or False: FRP wrapping increases the ductility of structural elements.

   • True
   • False

   Hint

   Remember its protective function.

5. 5.

   A building constructed in the 1980s didn't account for modern seismic standards. List and describe three retrofitting techniques that would enhance its ductility.

   Hint

   Think about the modern methods used to enhance older structures.

6. 6.

   Evaluate how FRP wrapping can be integrated into the design of an older concrete building and discuss potential challenges.

   Hint

   Consider the practical steps of applying new materials to older designs.
