Challenge Problems

Push your limits with challenges.

Question 1

A two-story building has modal participation factors of 0.6 for the first mode and 0.4 for the second. If the spectrum yields 8 units for the first mode and 5 units for the second, calculate the combined maximum response using SRSS.

💡 Hint: Remember to scale the modal responses by participation factors before applying SRSS.

Question 2

Discuss how non-classical damping can influence the results of Modal Response Spectrum Analysis in practical applications, and provide a theoretical example.

💡 Hint: Think about how damping changes the motion of structures during real-world seismic events.
