40.20. Base Isolation and Energy Dissipation Devices

Try these first

1. 1.

   What is the main purpose of base isolation?

   Hint

   Think about how buildings are affected during an earthquake.

2. 2.

   Name one type of damping device.

   Hint

   Consider devices that help with energy absorption.

3. 3.

   What is the primary function of base isolation devices?

   • Increase building weight
   • Reduce seismic force
   • Increase ground motion
   • None of the above

   Hint

   Think about how these devices interact with the foundation.

4. 4.

   True or False: Damping devices are mandatory by code.

   • True
   • False

   Hint

   Consider the current regulations regarding these technologies.

5. 5.

   Design a theoretical building in a seismic zone. How would you integrate base isolation and what types of damping devices would you consider?

   Hint

   Think about how different devices counteract specific types of seismic forces.

6. 6.

   Analyze the pros and cons of using a friction pendulum system. What situations may limit its effectiveness?

   Hint

   Consider the physical properties and mechanics involved.
