Discuss the implications of using a damping ratio of 10% versus 30% on the design of a high-rise building in a seismic zone.
💡 Hint: Consider how material properties change with different damping levels.
If an engineer is designing a base-isolated building with Sa calculated as 0.9g at 5% damping, what would the adjusted Sa be at 10% damping? Calculate using the correction factor.
💡 Hint: Refer to the correction factor table for precise calculations.
