Question 1.
What does base excitation refer to?
Show hintHide hint
Think about what happens to a building when the ground shakes.
Question 2.
Define relative displacement.
Show hintHide hint
What do we call the displacement of the structure compared to the ground?
3Question 3.
What is the primary model used to describe the response of structures to ground motion?
- Static load model
- Base excitation model
- Linear model
Show hintHide hint
Think about how we represent forces acting at the base.
4Question 4.
True or False: Relative displacement is not important in earthquake engineering.
- True
- False
Show hintHide hint
Consider how buildings would react if we ignored this concept.
Question 5.
Given a building with a height of 100m and average sway during an earthquake of 0.5m, calculate the relative displacement if the ground moves 0.3m.
Show hintHide hint
What is the difference between the two measurements?
Question 6.
Discuss how engineers can utilize response spectrum analysis to design a new skyscraper in an earthquake-prone area.
Show hintHide hint
Consider what factors influence the engineering design in such scenarios.
