1.18.1. Passive Control Devices

Try these first

1. 1.

   What is a base isolator?

   Hint

   Think about how it helps in an earthquake.

2. 2.

   Name one type of passive control device.

   Hint

   Focus on devices that require no external power.

3. 3.

   What do passive control devices do?

   • Require external power
   • Reduce vibrations without power
   • Increase building mass

   Hint

   Think of their role during an earthquake.

4. 4.

   Base isolators allow buildings to:

   • True
   • False

   Hint

   Consider the foundation of a building.

5. 5.

   Design a theoretical building using passive control technologies. Describe how you would incorporate base isolators, tuned mass dampers, and viscous wall dampers.

   Hint

   Consider the structure's height, location, and anticipated seismic activity.

6. 6.

   Evaluate an existing building's earthquake mitigation strategies. Discuss the effectiveness and areas for improvement.

   Hint

   Focus on a building that has experienced significant seismic events.
