Question 1.
Define effective mass in the context of SDOF systems.
Show hintHide hint
Think about how mass influences motion.
Question 2.
What does effective stiffness represent?
Show hintHide hint
Consider elasticity and structure stability.
3Question 3.
What does effective mass represent in SDOF systems?
- Total mass
- Mass participating in seismic response
- Mass of structural elements
Show hintHide hint
Focus on mass contribution during dynamic loads.
4Question 4.
Effective stiffness influences the structural response during seismic events.
- True
- False
Show hintHide hint
Remember how stiffness affects movement.
Question 5.
Given an SDOF structure with an effective mass of 500 kg and an effective stiffness of 10000 N/m, calculate the natural frequency.
Show hintHide hint
Use the formula ω = √(k/m) to find the frequency.
Question 6.
If an effective damping ratio is 0.05, how does this affect the structural response during a seismic event?
Show hintHide hint
Consider how damping impacts vibrations and movement.
