Question 1.
What does SSI stand for?
Show hintHide hint
Think about the interaction between soil and structures.
Question 2.
How do flexible soils affect structures?
Show hintHide hint
Recall what happens during an earthquake.
3Question 3.
What is the main effect of flexible soils on structures during seismic events?
- Increased displacement
- Decreased base shear
- Reduced periods
Show hintHide hint
Think about how structures behave on different soil types.
4Question 4.
True or False: Stiff soils amplify ground motion.
- True
- False
Show hintHide hint
Recall the behavior of rigid versus soft soils.
Question 5.
Consider a tall building designed under the assumption it is on stiff soil but the site is found to be soft clay. Discuss the potential issues that could arise during an earthquake.
Show hintHide hint
Think about how the unexpected soil type alters the original design assumptions.
Question 6.
Evaluate the benefits of including SSI analysis in tall building design codes and the risks if ignored.
Show hintHide hint
Consider what happens during a severe earthquake and its impact on tall structures.
