Question 2.
What does a DAF value greater than 1 indicate?
Show hintHide hint
Higher than what's normal?
3Question 3.
What does a DAF of greater than 1 indicate?
- No amplification
- Amplified motion
- Static behavior
Show hintHide hint
Think about whether the motion increases.
4Question 4.
True or False: DAF only applies to static loads.
- True
- False
Show hintHide hint
Consider if DAF relates to dynamic forces.
Question 5.
A structure experiences a maximum dynamic displacement of 15 cm and a static displacement of 5 cm. Calculate the DAF and discuss its implications in earthquake engineering context.
Show hintHide hint
Use the ratio of the two given displacements.
Question 6.
Examine a scenario where two buildings with different natural frequencies are subjected to the same dynamic load during an earthquake. How would their DAF values differ? Discuss the potential outcomes.
Show hintHide hint
Think about how frequency relations affect DAF.
