Question 1.
What are coupled modes?
Show hintHide hint
Consider how different movements can be linked.
Question 2.
Define torsional modes.
Show hintHide hint
Think of twisting instead of just moving back and forth.
3Question 3.
What do coupled modes involve?
- Only translation
- Only rotation
- Both translation and rotation
Show hintHide hint
Think about different movements happening at once.
4Question 4.
True or False: Torsional modes affect only symmetric structures.
- True
- False
Show hintHide hint
Consider what happens if weights are not balanced.
Question 5.
Analyze a structural model given its mass distribution and determine how torsional modes would affect its overall stability under seismic loads.
Show hintHide hint
Consider both lateral and rotational responses.
Question 6.
Given a case of an irregular building experiencing torsional behavior, suggest several engineering modifications to minimize damage during an earthquake.
Show hintHide hint
Focus on balancing the mass and stiffness across the structure.
