2 cards from this section. Quick, good the night before a test.
What is lumped mass idealization?
Think about how we model forces in a building.
What does the mass matrix [M] represent?
Focus on the structure's floors and their contribution to mass.
What does the mass matrix [M] represent in an MDOF system?
Which matrix talks about weights?
True or False: The stiffness matrix [K] is a diagonal matrix.
Consider the nature of the structure.
Given a structure with 4 floors, each with mass 1000 kg, and a stiffness of 10000 N/m for each floor, set up the mass and stiffness matrices.
Think about how mass and stiffness are distributed.
Analyze how damping affects an MDOF system subjected to harmonic loading.
Recall the significance of energy loss during oscillations.
