Question 1.
What is the purpose of convolution in structural dynamics?
Show hintHide hint
Think about the interaction between two functions.
Question 2.
Give an example of ground motion function.
Show hintHide hint
What function describes oscillations due to seismic waves?
3Question 3.
What does the convolution of f(t) and h(t) predict?
- Time taken for an earthquake
- Displacement of the building
- Amount of ground motion
Show hintHide hint
Consider the output effect of seismic activity.
4Question 4.
True or False: Convolution is solely used for time-series data analysis.
- True
- False
Show hintHide hint
Remember other fields where it's applied.
Question 5.
Given a building's impulse response function h(t) = \frac{1}{2} e^{-2t}, calculate the displacement response y(t) when subjected to f(t) = e^{-1.5t} \sin(3t).
Show hintHide hint
Remember to set limits of integration zero to t.
Question 6.
Discuss how changing the damping ratio in h(t) affects the building's response. Give a specific example.
Show hintHide hint
Think about energy dissipation in systems.
