Question 1.
What does Lumped Mass Idealization refer to?
Show hintHide hint
Think about where mass is commonly distributed in buildings.
Question 2.
In which analysis is the lumped mass idealization primarily used?
Show hintHide hint
This analysis helps determine natural frequencies of a structure.
3Question 3.
What is the primary benefit of lumped mass idealization?
- Increased complexity
- Simplification of models
