Question 1.
What is viscous damping?
Show hintHide hint
Think about how vibration energy is managed in structures.
Question 2.
State the equation for viscous damping.
Show hintHide hint
What does 'F' represent in the context of damping?
3Question 3.
What is the basic principle of viscous damping?
- a) Energy is added
- b) Force is proportional to velocity
- c) Force is independent of motion
Show hintHide hint
Remember the equation F = c·u˙(t).
4Question 4.
True or False: Viscous damping reduces energy dissipation in structures.
- True
- False
Show hintHide hint
Think about the function of damping.
Question 5.
Given a damping coefficient of 20 Ns/m and a maximum velocity of 8 m/s, calculate the maximum damping force. Discuss what that means for structural design.
Show hintHide hint
Use the damping force equation.
Question 6.
A structure is designed to resist earthquake forces with a damping ratio of 0.5. How does this ratio affect its performance compared to a structure with a damping ratio of 0.2?
Show hintHide hint
Compare the effects of different damping ratios on performance.
