Try these first

1. 1.

   What is the recommended mortar ratio discussed in the section?

   Hint

   Think about the mixture that helps maintain wall strength.

2. 2.

   Explain why symmetrical buildings are preferred in flood-prone areas.

   Hint

   Recall the importance of balance and symmetry.

3. 3.

   What is an important design feature to reduce flood vulnerability?

   • A) Many offsets
   • B) Symmetry
   • C) Irregular shapes

   Hint

   Consider equilibrium and balance in design.

4. 4.

   True or False: Building with a mortar ratio of less than 1:6 is acceptable for stability.

   • True
   • False

   Hint

   Recall the importance of material proportions.

5. 5.

   Propose a plan for retrofitting a coastal building that has experienced damage due to flooding.

   Hint

   Focus on understanding the damage and proposing effective solutions.

6. 6.

   Analyze the failure mechanisms of buildings built with inadequate mortar ratios during a flood event.

   Hint

   Consider how the strength of materials directly affects resilience.
