Challenge Problems
Push your limits with advanced challenges
Consider a 3-DOF MDOF system. After performing eigenvalue analysis, you determine three natural frequencies: 5 Hz, 10 Hz, and 20 Hz. Discuss how many modes you would consider essential for capturing significant dynamics if you're using the Modal Superposition Method.
💡 Hint: Remember that fewer modes can capture most of the behavior while saving computational effort.
Explain what factors would influence your decision on what modes to include when applying modal truncation in a seismic analysis context.
💡 Hint: Focus on how much each mode contributes to the total response.
