Question 1.
Explain how a cantilever beam reacts to dynamic loads.
Show hintHide hint
Think about how it moves under lateral forces!
Question 2.
What defines a dynamic degree of freedom?
Show hintHide hint
Remember we talked about movement in class.
3Question 3.
What is a dynamic degree of freedom?
- A static load point
- The means by which a structure can move under dynamic loads
- The mass of a structure
Show hintHide hint
Consider how structures respond to changing forces.
4Question 4.
True or False: A cantilever beam has multiple dynamic degrees of freedom.
- True
- False
Show hintHide hint
Refer to the class discussion on cantilever beams.
Question 5.
Explain how the dynamic analysis of a cantilever beam would differ from that of a multi-story frame when subjected to an earthquake.
Show hintHide hint
Refer to the complexities of analyzing each type of structure.
Question 6.
Discuss how the presence of multiple DOFs in a multi-story frame affects the overall stiffness of the structure during seismic events.
Show hintHide hint
Think about how forces are distributed in a multi-story building.
