Question 1.
What is Peak Ground Acceleration (PGA)?
Show hintHide hint
Think about what represents the strongest shaking during an earthquake.
Question 2.
Define Single Degree of Freedom (SDOF) system.
Show hintHide hint
Consider how masses move when pushed or pulled.
3Question 3.
What does Peak Ground Acceleration (PGA) represent?
- The lowest ground acceleration
- The maximum ground acceleration
- The average ground speed
Show hintHide hint
Focus on what would be the most intense shaking during an earthquake.
4Question 4.
True or False: SDOF systems capture complex multi-dimensional forces in structures.
- True
- False
Show hintHide hint
Remember the simplification aspect of SDOF.
Question 5.
Given an earthquake with a recorded PGA of 0.5g, calculate the potential structural response for an SDOF system with a mass of 1000 kg and a damping ratio of 5%.
Show hintHide hint
Think about how mass affects response under given ground accelerations.
Question 6.
Explain the effects of varying soil types on PGA and how this influences SDOF system results.
Show hintHide hint
What role does soil play in seismic wave propagation?
