Question 1.
What is coupling in structural dynamics?
Show hintHide hint
Think about how movements in one part might affect others.
Question 2.
Define torsional stiffness.
Show hintHide hint
Consider what happens when you twist a material.
3Question 3.
What is torsional coupling?
- A) Only affects translation
- B) Interaction between rotational and translational DOFs
- C) Only relevant in thin structures
- D) None of the above
Show hintHide hint
Focus on how different types of movements can impact each other.
4Question 4.
True or False: Complete decoupling is always achievable in irregular structures.
- True
- False
Show hintHide hint
Consider the structural irregularities that impede decoupling.
Question 5.
Describe how you would analyze a 10-story asymmetric building located in a seismically active area. Consider its modal properties and the coupling effects in your approach.
Show hintHide hint
Think about what steps would ensure you capture both translational and rotational behaviors.
Question 6.
Given a structure shows significant torsional amplification during an earthquake, suggest design modifications to improve its resilience.
Show hintHide hint
Consider how structural changes can redirect forces.
