Question 1.
What is the main purpose of seismic base isolation?
Show hintHide hint
Think about how the building's structure relates to ground movement.
Question 2.
Name one type of isolator used in seismic base isolation.
Show hintHide hint
Remember LRB as an important type.
3Question 3.
What is the primary function of seismic base isolation?
- To increase building height
- To decouple the structure from ground motion
- To elevate the building
Show hintHide hint
Focus on what it means to 'decouple' the structure.
4Question 4.
True or False: Friction Pendulum Systems are used to reduce lateral movement during an earthquake.
- True
- False
Show hintHide hint
Think about how the system operates during seismic events.
Question 5.
Design a comprehensive seismic isolation strategy for a 30-story building in a seismic zone, including the selection of isolators based on performance characteristics.
Show hintHide hint
Focus on factors like damping characteristics and material capabilities.
Question 6.
Compare and contrast the functions of Lead Rubber Bearings and Friction Pendulum Systems in seismic design. Which scenario would favor using one over the other?
Show hintHide hint
Analyze their operational principles and where they excel.
