What does PGA represent?
💡 Hint: Consider what the 'P' stands for.
True or False: The design acceleration spectrum decreases with increasing period for long-period structures.
💡 Hint: Relate this to how buildings behave during different types of seismic forces.

Challenge Problems
Push your limits with advanced challenges
If a building must be designed in Zone IV with a PGA of 0.24g, how would a structural engineer approach the design compared to one in Zone II, which has 0.10g?
💡 Hint: Think about the difference in numerical values for each zone and how that impacts structural integrity.
The amplification factor for a short-period structure is 1.5. If its base design needs to withstand a PGA of 0.24g, what would be the effective design PGA considered?
💡 Hint: Consider how multiplication affects scale when factoring in risks during an earthquake.
