34.11. Performance-Based Seismic Design (PBSD)

Try these first

1. 1.

   What does the acronym PBSD stand for?

   Hint

   Think about what this design aims to achieve in structures.

2. 2.

   Name the two earthquakes considered for life safety in PBSD.

   Hint

   They are the key events in PBSD for assessing life safety.

3. 3.

   What is the main goal of Performance-Based Seismic Design?

   • To prevent any damage under earthquakes
   • To limit damage and ensure function after seismic events
   • To focus solely on aesthetic design

   Hint

   Think about one of its key principles related to functionality.

4. 4.

   True or False: The Maximum Considered Earthquake (MCE) corresponds to the lowest seismic level considered in PBSD.

   • True
   • False

   Hint

   Which earthquake represents the most severe conditions?

5. 5.

   Propose a hypothetical community center designed using PBSD principles. Discuss how it would perform across the SLE, DBE, and MCE levels.

   Hint

   Consider the roles different structures play in a community and how they might need to function post-earthquake.

6. 6.

   Evaluate the implications of using nonlinear analysis in PBSD. Discuss potential challenges that might arise.

   Hint

   Think about how understanding the material response affects structural behavior and reliability.
