41.1. Philosophy of Earthquake Resistant Design

Try these first

1. 1.

   What does ductility refer to in earthquake-resistant design?

   Hint

   Think about how materials respond to stress during an earthquake.

2. 2.

   Name the three design levels in seismic design.

   Hint

   Think of them as increasing levels of intensity.

3. 3.

   What is the primary goal of earthquake-resistant design?

   • A) Allow full collapse
   • B) Ensure safety against collapse
   • C) Only prevent damage

   Hint

   Consider what is most important in design safety.

4. 4.

   True or False: Some damage is acceptable during a Maximum Considered Earthquake (MCE).

   • True
   • False

   Hint

   Think about the specifics of MCE design requirements.

5. 5.

   Consider a new building designed for MCE. Discuss what features it must include to ensure it meets the performance objectives and how ductility would play a role.

   Hint

   Think about what structural changes can add safety and flexibility.

6. 6.

   Analyze the potential consequences if a building designed only for OLE were subjected to a DBE. What risks could arise?

   Hint

   Consider what happens when a structure isn't resilient enough.
