Question 1
What is the primary characteristic of torsional mode shapes in frame structures?
- They primarily involve lateral translation.
- They result from asymmetrical distributions.
- They are non-existent.
💡 Hint: Consider what happens in asymmetrical buildings.
Question 2
True or False: Combined mode shapes can only occur in perfectly symmetrical frame structures.
- True
- False
💡 Hint: Think about how different shapes can react.

Challenge Problems
Push your limits with challenges.
Question 1
Consider a frame structure with an uneven distribution of mass. Using modal analysis, how would you determine the effects of both lateral translation and torsion in its design?
💡 Hint: Review eigenvalue problems from earlier sections.
Question 2
Design a frame structure intended to resist torsional forces. Outline key design elements that would help stabilize the building's response during lateral earthquakes.
💡 Hint: Think about methods to counteract twisting effects.
