Question 1.
What is fixed base analysis?
Show hintHide hint
Think about how a tree might stand tall and firm.
Question 2.
What does flexible base analysis consider?
Show hintHide hint
Consider what happens when you walk on a soft surface!
3Question 3.
What foundational type does fixed base analysis ignore?
- Flexibility
- Cost
- Safety
Show hintHide hint
Focus on the rigidity of the foundation.
4Question 4.
True or False: Flexible base analysis considers ground stiffness.
- True
- False
Show hintHide hint
Check how the structure interacts with the ground.
Question 5.
Consider a building designed with fixed base analysis in an area prone to earthquakes. What might be the practical consequences in terms of safety and performance?
Show hintHide hint
Think about how structural damage manifests during earthquakes.
Question 6.
Evaluate a scenario where a structure's design changes from fixed base to flexible base analysis. What changes would occur in the seismic response?
Show hintHide hint
Reflect on how flexibility helps mitigate seismic forces.
