4 cards from this section. Quick, good the night before a test.
What does modal analysis help us understand?
Think about breaking down movement into simpler parts.
What does SDOF stand for?
It refers to a simplified model of vibration.
What is modal analysis mainly used for?
Think of the types of loads that affect a structure over time.
True or False: The participation factor (Γ) only applies to SDOF systems.
Remember the broader application of participation in vibration analysis.
Given a structure with an estimated mass of 2000 kg and an effective stiffness of 50000 N/m, calculate the fundamental period T.
Use the T formula carefully.
A building has a first mode participation factor of 0.85. Discuss whether it can be effectively modeled as an SDOF system.
Consider the value threshold for SDOF representation.
