Challenge Problems
Push your limits with advanced challenges
Consider a building designed with a spectral acceleration factor (Sa/g) of 0.3 on a damping ratio of 5% on soft soil. Calculate the increase in spectral acceleration if the soil were to change to a stiffer type.
💡 Hint: Refer to codes that specify how soil type can factor into spectral calculations.
A building experiences high levels of shaking during a seismic event. How would a higher damping ratio mitigate the effects on the structure compared to a lower one?
💡 Hint: Think about the concept of energy dissipation in materials.
