32.15.4. Seismic Isolation and Energy Dissipation Systems

Try these first

1. 1.

   Define seismic isolation.

   Hint

   Think about how a structure reacts during an earthquake.

2. 2.

   What are lead rubber bearings?

   Hint

   Consider the materials that help in managing seismic forces.

3. 3.

   What is the primary function of seismic isolation systems?

   • To increase building height
   • To allow independent movement from ground motion
   • To reduce weight of the structure

   Hint

   Think about how structures move during an earthquake.

4. 4.

   True or False: Friction Pendulum Systems use rolling motion to dissipate energy.

   • True
   • False

   Hint

   Consider how these systems are designed to counteract movement.

5. 5.

   Design a building utilizing both a seismic isolation and an energy dissipation system. Describe where and how you would implement these systems effectively.

   Hint

   Think about the source of forces on the building.

6. 6.

   Evaluate the performance of a structure that incorporates only energy dissipation systems but lacks seismic isolation. How might this impact durability during an earthquake?

   Hint

   Consider the interaction between energy movement and structural integrity.
