Question 1.
What is the purpose of base isolation?
Show hintHide hint
Think about earthquake protection.
Question 2.
Describe inter-storey drift in base-isolated structures.
Show hintHide hint
Consider how floors behave in an earthquake.
3Question 3.
What is the main function of base isolation?
- To withstand seismic forces
- To decouple the building from ground motion
- To increase building weight
Show hintHide hint
Think about the relationship between the building and the ground.
4Question 4.
True or False: Most displacement in a base-isolated building occurs at the upper floors.
- True
- False
Show hintHide hint
Recall the definition of how base isolation works.
Question 5.
Design a simple model for a base-isolated building and describe how you would test its effectiveness against seismic forces.
Show hintHide hint
Think about the materials you would use and the mechanism of isolation.
Question 6.
Evaluate the performance implications of a base-isolated structure compared to a traditional fixed-base system during a simulated earthquake scenario. What metrics would you compare?
Show hintHide hint
Focus on qualitative and quantitative aspects to derive the full comparison.
