40.22. Seismic Design Categories and Importance Classifications

Try these first

1. 1.

   What is a seismic design category?

   Hint

   Think about the factors that influence building codes.

2. 2.

   Name an example of a high-importance structure.

   Hint

   Consider buildings that must remain functional during a disaster.

3. 3.

   What is a high-importance structure classified based on?

   • Structural system only
   • Occupancy type only
   • Both occupancy type and structural system

   Hint

   Consider how different types of buildings serve different purposes.

4. 4.

   True or False: A hospital has a lower Importance Factor (I) than an ordinary building.

   • True
   • False

   Hint

   Think about the role a hospital plays in an emergency.

5. 5.

   Given a seismic zone classification for a large hospital located in a high-risk area, identify how the design specifications should change compared to a standard office building.

   Hint

   Reflect on how the role and use of the building affects its design.

6. 6.

   How would you justify the upgraded ductility requirements for emergency response centers in comparison to standard residential buildings?

   Hint

   Think about the critical functions these buildings serve.
