1.11. Vibration Isolation and Control

Try these first

1. 1.

   What is base isolation?

   Hint

   Think about how structures can 'float'.

2. 2.

   Define Tuned Mass Damper.

   Hint

   Focus on the idea of 'tuning' for vibrations.

3. 3.

   What is the primary purpose of vibration isolation?

   • To enhance building aesthetics
   • To reduce seismic forces
   • To increase building height

   Hint

   Think about what happens during an earthquake.

4. 4.

   True or False: Tuned Mass Dampers can operate without external power.

   • True
   • False

   Hint

   Consider if they need any active intervention.

5. 5.

   Design a short narrative describing a scenario where a building uses both base isolation and tuned mass dampers during an earthquake.

   Hint

   Focus on how the two systems work together to minimize structural movement.

6. 6.

   Analyze the potential effects of a poorly designed active control system in a high-rise building during an earthquake.

   Hint

   Think about the relationship between feedback and structural response.
