Question 1.
What is an SDOF system?
Show hintHide hint
Think about how many ways a building can move in a simple model.
Question 2.
Why are SDOF systems easier to analyze than MDOF systems?
Show hintHide hint
Remember, less complexity means easier analysis.
3Question 3.
What is the primary characteristic of an SDOF system?
- Multiple degrees of freedom
- One degree of freedom
- Complex analysis
Show hintHide hint
Remember SDOF means single!
4Question 4.
MDOF systems are primarily used for which type of structures?
- Simple structures
- Regular low-rise buildings
- Complex
- irregular buildings
Show hintHide hint
Think about buildings that are not straight and even.
Question 5.
Given a building design scenario, evaluate if it should be modeled using SDOF or MDOF. Justify your answer with at least three reasons.
Show hintHide hint
Consider the design's physical features and expected behavior in earthquakes.
Question 6.
Explain how neglecting torsional effects in an MDOF system can lead to inaccurate predictions in seismic analysis.
Show hintHide hint
Think about how twisting can influence a building's stability during an earthquake.
