Challenge Problems
Push your limits with advanced challenges
Given a set of response spectra from three different earthquakes, describe how you would scale each spectrum to match a target PGA of 0.5g and then average the results.
💡 Hint: Utilize the formula for scaling based on ratios.
If two scaled response spectra show significant disparity in their periods, analyze how averaging them could yield a misleading average spectrum.
💡 Hint: Consider if both spectra could represent similar ground motion characteristics.
