42. Base Isolation Techniques

Try these first

1. 1.

   What is base isolation?

   Hint

   Think of it as a way to protect buildings during earthquakes.

2. 2.

   Name one type of isolation bearing.

   Hint

   Focus on the material used.

3. 3.

   What is the primary function of base isolation?

   • To increase strength
   • To reduce seismic impact
   • To modify building materials

   Hint

   Remember the goal of seismic protection.

4. 4.

   True or False: Base isolation is only effective for new constructions.

   • True
   • False

   Hint

   Think about how it can apply to both categories.

5. 5.

   Design a base isolation system for a medium-rise hospital. Discuss the types of bearings to use, the damping mechanisms to integrate, and potential challenges based on location.

   Hint

   Think about both the mechanical and environmental aspects.

6. 6.

   Evaluate the performance of a base-isolated building compared to a fixed-base design during an earthquake. Discuss parameters like inter-storey drift and damage.

   Hint

   Consider how motion transfer differs between the two systems.
