Challenge Problems
Push your limits with advanced challenges
A new bridge in a seismic zone requires a Sa vs. T curve for analysis. Given the average period of the bridge is about 0.8s, select historical earthquake records and scale them to match a UHS representing a 10% probability of exceedance in 50 years.
💡 Hint: Consider the geological conditions of the site and its corresponding seismicity.
Discuss the potential consequences of using inadequate ground motion data in the seismic analysis of a new hospital design.
💡 Hint: Reflect on the importance of safety in critical infrastructure.
