44.10. Retrofitting and Strengthening of Existing Structures

Try these first

1. 1.

   What is one reason for retrofitting older buildings?

   Hint

   Think about the building's original design standards.

2. 2.

   Name one retrofitting technique.

   Hint

   Consider methods used to increase strength.

3. 3.

   Why is retrofitting necessary for older buildings?

   • To beautify them
   • To repair damage and enhance seismic safety
   • To change their function

   Hint

   Think about the risks involved with old buildings during earthquakes.

4. 4.

   True or False: Retrofitting can increase a building's resilience to seismic forces.

   • True
   • False

   Hint

   Consider the impact of safe structures in an earthquake.

5. 5.

   Design a retrofitting plan for a fictional building that was built in the 1970s, detailing at least three specific strategies you would employ and justify their effectiveness in increasing seismic resistance.

   Hint

   Consider the materials and structural weaknesses common in that era.

6. 6.

   Explain how the cost of retrofitting impacts the decision-making process for building owners, and what may influence them to choose to retrofit or not.

   Hint

   Think about the financial versus safety implications in your explanation.
