44. Important Points in Mitigating Effects of Earthquake on Structures

Try these first

1. 1.

   What is liquefaction?

   Hint

   Think about how soil behaves during strong shaking.

2. 2.

   Name one benefit of redundancy in a structure.

   Hint

   Consider what happens if a beam or column fails.

3. 3.

   What is the primary purpose of seismic isolation?

   • To strengthen the building
   • To separate the structure from ground motion
   • To reduce building height

   Hint

   Remember the concept of flexibility in design.

4. 4.

   Redundancy in structural design refers to:

   • True
   • False

   Hint

   Consider what happens in a system with multiple paths.

5. 5.

   Analyze a building designed with significant overhangs. Discuss potential seismic risks and propose design alterations to mitigate those risks.

   Hint

   Consider how shifting weight balances can affect a building's performance.

6. 6.

   Consider an older masonry building retrofitted with steel bracing. Analyze the impact this will have on the building’s earthquake resistance.

   Hint

   Think about how adding stronger materials can strengthen structures.
