31.5.1. Bridges and Flyovers

Try these first

1. 1.

   What is predictive maintenance?

   Hint

   Think about how we can use data to avoid sudden breakdowns.

2. 2.

   How are drones used in bridge inspections?

   Hint

   Consider the benefits of not needing to send people up there.

3. 3.

   What is the primary advantage of using drones for bridge inspections?

   • Speed
   • Cost
   • Safety
   • All of the above

   Hint

   Think about all the ways drones outperform traditional methods.

4. 4.

   True or False: Monitoring joint displacements can help predict possible structural failures.

   • True
   • False

   Hint

   Consider what can happen to structures with too much movement.

5. 5.

   Design a basic maintenance plan for a bridge using predictive maintenance technologies. Include drone inspections and vibration analysis.

   Hint

   Think about the types of technology you've learned and how often inspections would be practical.

6. 6.

   Evaluate a scenario where a bridge exhibits significant vibration changes over time. What steps should engineers take?

   Hint

   Recall the reasons changes in vibrations can be a sign of a bigger issue.
