42.3. Types of Base Isolation Systems

Try these first

1. 1.

   What is an elastomeric isolation system?

   Hint

   Think about the materials used in the system.

2. 2.

   Describe one main feature of lead rubber bearings.

   Hint

   Focus on the internal components of the bearing.

3. 3.

   What is the primary function of base isolation systems?

   • To strengthen buildings
   • To absorb seismic forces
   • To increase weight

   Hint

   Think about what happens during an earthquake.

4. 4.

   True or False: Lead rubber bearings provide energy dissipation.

   • True
   • False

   Hint

   Focus on the role of the lead core in these bearings.

5. 5.

   Propose a scenario where hybrid systems would outperform individual base isolation systems. Discuss how you would assess performance measures.

   Hint

   Think about which isolator features maximize safety and resilience.

6. 6.

   Evaluate the implementation of lead rubber bearings in a high-rise building located on soft soil. What challenges might arise, and how could they be mitigated?

   Hint

   Consider the influence of soil types on seismic response.
