Question 2.
Name one piece of equipment used in Forced Vibration Tests.
Show hintHide hint
What device measures acceleration and vibrations?
3Question 3.
What is the primary purpose of a Forced Vibration Test?
- To apply realistic strains to structures
- To measure the response to an applied force
- To observe ambient vibrations
Show hintHide hint
Think about the main goal of applying controlled forces.
4Question 4.
True or False: Ambient Vibration Tests are preferred over Forced Vibration Tests because they are less invasive.
- True
- False
Show hintHide hint
Consider the invasiveness of the testing methods.
Question 5.
Suppose a building has a natural frequency of 2 Hz. During a Forced Vibration Test, an external force applied is at 2 Hz. What phenomenon occurs, and what are its implications for the building?
Show hintHide hint
Relate to what happens when external frequency matches the natural frequency.
Question 6.
Consider a scenario where a historical building is subjected to a Forced Vibration Test. Discuss the ethical and structural considerations that must be taken into account.
Show hintHide hint
Balance between safety data needs and preservation.
