Show hintHide hint
Recall the context of mass excitation.
4Question 4.
True or False: Base excitation is indirect and involves the structure's base movements.
- True
- False
Show hintHide hint
Think about what base excitation means.
Question 5.
A building is designed to withstand both wind and seismic loads. Discuss how mass excitation and base excitation influence the design criteria.
Show hintHide hint
Think about how different loads affect design choices.
Question 6.
Given the equation of motion for base excitation, how would an increase in ground acceleration affect the structural response?
Show hintHide hint
Recall the implications of the EOM in response to increased acceleration.
