4 cards from this section. Quick, good the night before a test.
Define what an MDOF system is.
What does MDOF stand for?
Give one example of MDOF systems.
Think of structures with multiple components that move.
What does MDOF stand for?
Focus on degrees and freedom in structural terms.
True or False: An SDOF system is sufficient for modeling the behavior of complex structures.
Consider why multiple degrees might be necessary.
Given a 3-story building modeled as an MDOF system, where each floor has different masses and stiffnesses, derive the coupled differential equations governing their motion.
Think about how the motion of one floor affects the others.
Explain the impact of neglecting the coupled nature of MDOF systems in seismic design.
Consider how dynamics should account for interactions, not just isolated events.
