1.18. Vibration Control Devices in Modern Structures

Try these first

1. 1.

   Define passive control devices and provide an example.

   Hint

   Think of how structures can be designed to work without extra energy.

2. 2.

   What is the function of a tuned mass damper?

   Hint

   Remember how the tuning aspect works.

3. 3.

   What is a passive control device?

   • A device requiring external power.
   • A device operating without external power.
   • A device only made from smart materials.

   Hint

   Consider how it functions during earthquakes.

4. 4.

   True or False: Active control systems apply forces in real-time.

   • True
   • False

   Hint

   Think about the immediate response capability.

5. 5.

   Analyze the benefits and disadvantages of using only passive control systems in regions with high seismic activity.

   Hint

   Examine real-world earthquake scenarios.

6. 6.

   Propose a hybrid vibration control strategy that encompasses passive, active, and smart materials for a new skyscraper in a seismic zone.

   Hint

   Look at how these technologies can complement each other.
