Question 1.
What does a Tuned Mass Damper (TMD) do?
Show hintHide hint
Think about vibrations control.
Question 2.
Name one effect of TMDs.
Show hintHide hint
Consider what happens during an earthquake.
3Question 3.
What is the main function of a Tuned Mass Damper?
- To absorb shock
- To reduce vibrations
- To increase resonance
Show hintHide hint
Consider its purpose in controlling forces.
4Question 4.
True or False: TMDs can only be used in buildings taller than 30 stories.
- True
- False
Show hintHide hint
Focus on where vibrations occur.
Question 5.
Design a theoretical TMD for a hypothetical high-rise building with a natural frequency of 0.5 Hz to explicitly counteract dynamic loading by an external force oscillating also at 0.5 Hz. Discuss the considerations you would need to account for in your design.
Show hintHide hint
Think about how natural frequencies can reinforce or counteract each other.
Question 6.
Evaluate the impact of TMDs on a structure with irregular shapes and natural frequencies above 1 Hz concerning seismic events. Would TMDs still be effective, or would alternative solutions be required?
Show hintHide hint
Consider how different building shapes influence oscillation patterns.
