Question 1.
What is base isolation?
Show hintHide hint
Think about how buildings can be protected during an earthquake.
Question 2.
What is spectral acceleration?
Show hintHide hint
It relates to the behavior of structures during earthquakes.
3Question 3.
What is the primary purpose of base isolation in seismic design?
- Increase building height
- Reduce seismic forces
- Improve aesthetic appeal
Show hintHide hint
Think about how buildings should react during earthquakes.
4Question 4.
True or False: A higher spectral acceleration indicates a safer building during earthquakes.
- True
- False
Show hintHide hint
Reflect on what lower values suggest about structural safety.
Question 5.
Calculate the expected spectral acceleration for a base-isolated structure with a damping ratio of 20% given a reference Sa of 1.5m/s2.
Show hintHide hint
Remember to apply the damping correction factors provided.
Question 6.
Critically assess the impact of using a damping ratio of 10% versus 30% on the performance of a base-isolated hospital.
Show hintHide hint
Relate force reductions to operational efficiency within critical facilities.
