43.3.2. Base Isolation Systems

Try these first

1. 1.

   What is the purpose of base isolation?

   Hint

   Think about how buildings can 'float' during an earthquake.

2. 2.

   Name one type of base isolator.

   Hint

   Look for types that help absorb shocks.

3. 3.

   What is the main purpose of base isolation systems?

   • To improve structural aesthetics
   • To reduce seismic forces
   • To increase building height

   Hint

   Remember the system's essence.

4. 4.

   True or False: Friction pendulum bearings work by allowing sliding movement to dissipate energy.

   • True
   • False

   Hint

   Think about their mechanism.

5. 5.

   Design a base isolation system for a hypothetical 10-story building in an earthquake-prone area. Discuss the types of isolators you would use and why.

   Hint

   Consider the height and building type when selecting isolators.

6. 6.

   Analyze how environmental factors, like temperature and aging, could impact the performance of base isolation systems. Propose solutions to mitigate these effects.

   Hint

   Think about how you keep your car in good condition over the years.
