4.11. Experimental Validation and Structural Monitoring

Try these first

1. 1.

   What does SHM stand for?

   Hint

   Think about what kind of monitoring it involves.

2. 2.

   Name one device used in SHM.

   Hint

   What device measures vibrations in structures?

3. 3.

   What is the primary function of accelerometers in structural health monitoring?

   • To measure temperature
   • To measure vibration
   • To measure weight

   Hint

   Focus on the types of data needed for monitoring.

4. 4.

   Negative damping ratio indicates a stable system.

   • True
   • False

   Hint

   Think about the implications of a damping ratio in structural behavior.

5. 5.

   You are given data from accelerometers on a newly built bridge. The results show complex roots in the analysis of its vibrations. What actions will you take? Discuss the potential implications of these findings.

   Hint

   Consider the impact of continuous data collection versus one-time analysis.

6. 6.

   A highway overpass experiences an unexpected amount of vibration after truck traffic increases. Discuss how you would apply SHM to this scenario and the steps needed to evaluate the structural integrity.

   Hint

   Think about what data you need and how it will inform your analysis.
