4Question 4.
True or False: FFT can be applied in monitoring wind loads on buildings.
- True
- False
Show hintHide hint
Consider the importance of wind forces on tall structures.
Question 5.
A civil engineer is monitoring a suspension bridge using FFT and notices a peak frequency that matches a known resonance frequency. What steps should the engineer take to ensure the structure's safety?
Show hintHide hint
Consider what can be done when a structure shows concerning signs in monitoring data.
Question 6.
During a dynamic soil test, FFT data shows unexpected wave speeds. How might this affect the foundation design, and what adjustments should be made?
Show hintHide hint
Think about how soil characteristics influence building stability.
