2 cards from this section. Quick, good the night before a test.
What is lumped mass idealization?
Think about how mass is represented in structural models.
Why do engineers use lumped mass idealization?
Consider the benefits of reducing complexity.
What does the lumped mass idealization focus on in structural modeling?
Think about how the masses are represented in the model.
True or False: Damping is not considered in lumped mass idealization.
Remember the role of energy dissipation.
A 6-story building is modeled using lumped mass idealization with masses of 1000 kg per floor. If each spring representing stiffness has a constant of 5000 N/m, calculate the natural frequency of the system.
Remember the formula for calculating natural frequency.
Discuss how using lumped mass idealization could impact the seismic design of a complex structure fitted with numerous irregularities.
Consider the balance between simplification and accuracy in structural behavior.
