Question 1.
What is the formula for calculating the amplification factor?
Show hintHide hint
Think about what each variable represents.
Question 2.
If a structure has a static deflection of 1 meter and dynamic response of 2 meters, what is the AF?
Show hintHide hint
Use the given formula.
3Question 3.
What does the amplification factor measure?
- The ratio of static to dynamic response
- The ratio of dynamic to static response
- The total displacement of a structure
Show hintHide hint
Think about how responses differ when forces are applied.
4Question 4.
True or False: A higher amplification factor indicates less risk for structural failure.
- True
- False
Show hintHide hint
Reflect on what high AF might indicate about vibrations.
Question 5.
A newly constructed skyscraper has a static deflection of 0.3 m. During simulation testing under dynamic loads, it shows a response of 1.5 m. Discuss the implications this amplification factor has for safety and design modifications.
Show hintHide hint
Think about safety implications and design adaptability.
Question 6.
Given a building undergoes a dynamical analysis revealing an AF of 6, how would you propose to mitigate this risk through design changes? Provide a detailed explanation.
Show hintHide hint
Focus on engineering principles that minimize vibration.
