38.10. Ductility in Different Structural Systems

Try these first

1. 1.

   What is ductility?

   Hint

   Think about a material's ability to bend versus break.

2. 2.

   Name one advantage of ductility in structures.

   Hint

   Consider what happens during an earthquake.

3. 3.

   Which structural system has the highest ductility?

   • Steel Moment Frames
   • Masonry Structures
   • Braced Frames

   Hint

   Consider the best performers in earthquakes.

4. 4.

   True or false: Ductility is only the property of materials.

   • True
   • False

   Hint

   Think about how different systems react under stress.

5. 5.

   Consider a scenario where a new design of a bridge integrates ductility features into its beams and columns. Describe how these features would impact the bridge's performance during an earthquake.

   Hint

   Focus on the roles of specific design features in resisting seismic forces.

6. 6.

   You are tasked with retrofitting an old masonry building for earthquake resilience. What modifications would you recommend to improve its ductility?

   Hint

   Think about the weaknesses of masonry structures under seismic loads and how you can address them.
