Challenge Problems
Push your limits with advanced challenges
Given a multi-degree-of-freedom system with specified mode shapes and participation factors, derive the total response under a known dynamic load. Consider different damping ratios in your evaluation.
💡 Hint: Remember to consider how damping ratios can alter mode contributions effectively.
Analyze a case where the completeness fails due to a non-linear response in a real structure. Provide an extensive explanation of the implications and potential solutions.
💡 Hint: Think about dynamic loads that could change behavior unexpectedly.
