Question 1.
What is the formula for relative displacement?
Show hintHide hint
Think about how we define the movement of a mass relative to the ground.
Question 2.
If a mass displaces 0.8m during an earthquake with a ground displacement of 0.4m, what is the relative displacement?
Show hintHide hint
Use the formula for relative displacement.
3Question 3.
What is relative displacement?
- The movement of a mass.
- The difference between mass displacement and ground movement.
- The total displacement of a structure.
Show hintHide hint
Think about what 'relative' means.
4Question 4.
True or False: Increased damping always decreases relative displacement.
- True
- False
Show hintHide hint
Connect damping with energy dissipation.
Question 5.
A building oscillates with a natural period of 1.5 seconds during an earthquake. If the mass displaces 0.75m and the ground moves 0.5m during shaking, find the relative displacement and evaluate the significance of the results.
Show hintHide hint
Use the subtraction mentioned for ur.
Question 6.
Discuss how varying levels of damping in structures affect their response to earthquake motions. Provide examples of structures with high and low damping characteristics.
Show hintHide hint
Consider examples of damping systems in real structures.
