Challenge Problems

Push your limits with challenges.

Question 1

A building modeled as an MDOF system has the following spectral accelerations for three modes: 0.8g, 1.2g, and 1.5g. If the modal participation factors are 0.4, 0.3, and 0.3 respectively, compute the peak modal response.

💡 Hint: Apply the peak response formula accordingly.

Question 2

For a dual-mode system where the spectral accelerations are 50 cm/s² for the first mode and 70 cm/s² for the second mode, and their respective modal participation factors are 0.6 and 0.4, calculate the combined peak response using CQC.

💡 Hint: Use the CQC formula to blend the results.
