Question 1.
What does the V/H ratio represent?
Show hintHide hint
Think about how vertical and horizontal ground motions relate.
Question 2.
What is a typical range for the V/H ratio?
Show hintHide hint
Recall the numbers that represent this ratio from our discussions.
3Question 3.
What is the typical range for the V/H ratio?
- 0.1 to 0.2
- 0.3 to 0.7
- 0.8 to 1.0
Show hintHide hint
Recall our discussions on V/H ratio values.
4Question 4.
True or False: The V/H ratio is unnecessary in the design of tall buildings.
- True
- False
Show hintHide hint
Consider the forces acting on tall structures during an earthquake.
Question 5.
An engineer observes that during a seismic event, the vertical response at a site required a V/H ratio of 0.45 for accurate design. If the site-specific horizontal spectrum has a peak ground acceleration (PGA) of 0.8g, what is the adjusted vertical PGA?
Show hintHide hint
Use the scaling formula involving V/H to adjust the values accordingly.
Question 6.
Discuss the potential consequences of applying a uniform V/H ratio of 0.5 across different soil types when designing a multi-story building. How would your approach differ if the building were to be constructed on soft soil versus hard rock?
Show hintHide hint
Consider how soil characteristics affect ground response.
