Question 1.
What is dynamic excitation?
Show hintHide hint
Think about loads that change over time.
Question 2.
Name one example of a dynamic load.
Show hintHide hint
Consider natural disasters affecting structures.
3Question 3.
What distinguishes dynamic excitation from static loads?
- Static loads are always higher
- Dynamic loads vary over time
- Static loads include vibrations
Show hintHide hint
Consider the behavior of forces during natural events.
4Question 4.
True or False: Inertia effects are negligible in dynamic excitation.
- True
- False
Show hintHide hint
Think about how mass reacts to changes.
Question 5.
A building is designed to withstand static loads only. During an earthquake, it experiences significant amplifications due to resonance. Discuss the implications and what design changes could improve its resilience.
Show hintHide hint
Think about how structures are tested for various load types.
Question 6.
From the above equation of motion, determine how would you modify the response of a structure under dynamic loading if the damping matrix C is increased. Explain the effects this could have.
Show hintHide hint
Consider how damping affects oscillations in physical systems.
