Question 1

What does the Modal Participation Factor indicate about a mode's contribution?

  • It is irrelevant
  • It quantifies the mode's contribution
  • It only applies to rigid structures

💡 Hint: Think about the purpose behind calculating MPF.

Question 2

True or False: Higher modes always have a significant contribution to seismic response.

  • True
  • False

💡 Hint: Consider the type and flexibility of the structure.

Challenge Problems

Push your limits with challenges.

Question 1

Given a structure with the first five modes' MPFs calculated, how would you decide whether to include additional modes in your simulation? What considerations would guide your decision?

💡 Hint: Evaluate both the numerical results and the characteristics of the structure.

Question 2

A seismic evaluation reveals that mode 3 has a significantly lower MPF compared to modes 1 and 2. Discuss potential reasons and implications for excluding mode 3 from the analysis.

💡 Hint: Think critically about structural behaviors and the significance of various modes.
