Challenge Problems

Push your limits with challenges.

Question 1

Consider a structure modeled using the mode superposition method. If truncation resulted in excluding three significant higher modes, analyze how this decision might affect the predicted response during an earthquake.

💡 Hint: Consider what each mode might contribute during an extreme event.

Question 2

Given a structure that has shown evidence of nonlinear behavior, discuss which analysis method you would recommend and why the mode superposition would not be appropriate.

💡 Hint: Think about how the system might change under load.
