Question 1.
What is pseudo-acceleration?
Show hintHide hint
Think about its relation to actual acceleration and angular frequency.
Question 2.
Define pseudo-velocity.
Show hintHide hint
Remember it is calculated with frequency.
3Question 3.
What does pseudo-acceleration represent?
- Actual acceleration
- An approximation of peak acceleration
- None of the above
Show hintHide hint
It's a measure used in seismic design.
4Question 4.
True or False: Pseudo-velocity is calculated using the angular frequency.
- True
- False
Show hintHide hint
Think about the relationship between these quantities.
Question 5.
Calculate the pseudo-acceleration for a structure with an angular frequency of 5 rad/s and an actual acceleration response spectrum value of 10 m/s².
Show hintHide hint
Remember to square the angular frequency.
Question 6.
Discuss how the use of pseudo-velocity allows for quicker assessments in engineering. What might be the trade-offs?
Show hintHide hint
Consider the balance between speed and accuracy in engineering design.
