Challenge Problems
Push your limits with advanced challenges
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.
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.
