Challenge Problems

Push your limits with challenges.

Question 1

Given a specific ground motion profile, determine the response of a structure with parameters m = 2500 kg, c = 500 N·s/m, and k = 100000 N/m. Use Duhamel's Integral for your calculations.

💡 Hint: Pay attention to defining the impulse response function correctly based on damping.

Question 2

Examine how variations in damping ratios affect the response of the structure during an earthquake. What are the implications if the damping ratio is increased significantly?

💡 Hint: Compare with different damping scenarios and their impacts on structural stability.
