Show hintHide hint
Remember what 'degree of freedom' means.
Question 2.
Define dynamic loading.
Show hintHide hint
Think of earthquakes and strong winds.
3Question 3.
What represents ground acceleration in the equations of motion?
- {u''(t)}
- {u''_g(t)}
- {f(t)}
Show hintHide hint
Think about what device senses the ground's movement.
4Question 4.
True or False: The modal superposition method only works for undamped systems.
- True
- False
Show hintHide hint
Focus on the versatility of the technique.
Question 5.
Given an MDOF system with specific parameters, derive the equations of motion and apply modal superposition to solve for displacements under dynamic loading.
Show hintHide hint
Refer back to definitions and previous examples listed in the notes.
Question 6.
Analyze how changes in ground acceleration impact the overall response of an MDOF system under seismic loading.
Show hintHide hint
How do you expect buildings to react to stronger or weaker ground shakes?
