2.7. Advanced Damping Devices in Seismic Design

Try these first

1. 1.

   What is a Tuned Mass Damper?

   Hint

   Think about how a weight can balance out forces.

2. 2.

   What does a Base Isolator do?

   Hint

   Consider how a cushion absorbs shock.

3. 3.

   What is the main purpose of Tuned Mass Dampers?

   • To enhance the appearance of buildings
   • To reduce vibrations caused by external forces
   • To increase structural mass

   Hint

   Think about how they work during windy or seismic conditions.

4. 4.

   Base isolators help to prevent seismic forces from reaching the building. True or False?

   • True
   • False

   Hint

   Consider their role during an earthquake.

5. 5.

   Design a tall building with TMDs and Base Isolators and explain how these devices work together to protect it from seismic hazards.

   Hint

   Consider how each device responds differently to seismic forces.

6. 6.

   Critique the effectiveness of using solely viscous dampers in a seismic design without TMDs or Base Isolators. What challenges could arise?

   Hint

   Think about how different forces affect building movements.
