Challenge Problems
Push your limits with advanced challenges
A ground motion record shows peak acceleration of 0.6g, but the design response spectrum requires 0.9g. If uniform scaling is used, what is the scaling factor and how might this impact the accuracy?
💡 Hint: Consider dividing the desired acceleration by the recorded value.
In a study, engineers want to apply spectral matching to a recorded ground motion that primarily affects high frequencies. How should they approach this task? Discuss any potential limitations.
💡 Hint: Reflect on the significance of incorporating all frequencies in the matching process.
