Question 1.
What does the mass matrix [M] represent?
Show hintHide hint
Think about inertia.
Question 2.
What role does the damping matrix [C] play?
Show hintHide hint
Consider how to control energy dissipation.
3Question 3.
What does the [K] matrix in the equations of motion represent?
- Mass distribution
- Energy dissipation
- Stiffness of the structure
Show hintHide hint
Consider how strong materials respond to forces.
4Question 4.
True or False: The mass matrix [M] affects how acceleration influences movement in MDOF systems.
- True
- False
Show hintHide hint
Think of inertia's impact during an earthquake.
Question 5.
Given a structure with specified mass and stiffness values, derive the system's response under a known oscillating force.
Show hintHide hint
Consider how mass, damping, and stiffness relate to displacement.
Question 6.
Analyze a scenario where neglecting damping in a seismic evaluation led to a failure in structural integrity. What measures would you recommend to rectify such an oversight?
Show hintHide hint
Reflect on past engineering failures due to inadequate design.
