Question 1

What does ground motion selection involve?

  • Choosing random records
  • Selecting records that reflect site seismicity
  • Ignoring past data

💡 Hint: Think about the characteristics of the earthquake events.

Question 2

Scaling ground motions is necessary to match what?

  • Random values
  • Target response spectrum
  • Historical data

💡 Hint: Match it to the spectrum used in seismic design.

Challenge Problems

Push your limits with challenges.

Question 1

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.

Question 2

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.
