14.1. Seismic Design Principles

Try these first

1. 1.

   What are ductile connections?

   Hint

   Consider what happens when a material bends.

2. 2.

   Define moment-resistant frames.

   Hint

   Think about stability during shaking.

3. 3.

   What is the purpose of ductile connections in a structure?

   • To allow movement during shaking
   • To increase weight
   • To weaken structure

   Hint

   Think about how flexibility relates to earthquakes.

4. 4.

   Moment-resistant frames are used in which type of structures?

   • True
   • False

   Hint

   Consider how structures stay stable.

5. 5.

   Design a simple floor plan using both precast and cast-in-situ components, ensuring to include provisions for ductile connections and progressive collapse prevention.

   Hint

   Think about where failure might occur and how to mitigate risks.

6. 6.

   Evaluate the impact of ignoring base isolation in a seismic-prone region. Discuss potential building flaws and safety hazards.

   Hint

   Consider a building that has no room to move with the shaking.
