Try these first

1. 1.

   What is the purpose of a site-specific response spectrum?

   Hint

   Think of what makes different locations unique in terms of earthquakes.

2. 2.

   Name one type of structure that benefits from site-specific response spectra.

   Hint

   Consider structures that require a high level of safety due to their function.

3. 3.

   What is a site-specific response spectrum designed to represent?

   • Only the average ground movement.
   • Unique seismic responses for a specific location.
   • Generic seismic responses applicable everywhere.

   Hint

   Think of terms like 'unique' vs 'average'.

4. 4.

   True or False: Site-specific spectra ensure that structures always overperform in seismic assessments.

   • True
   • False

   Hint

   Consider the meaning of 'overperform' and what it's compared to.

5. 5.

   Evaluate a new construction site that sits atop soft clay versus hard rock. Analyze how each site might respond differently during a seismic event and the implications for structural design.

   Hint

   Consider how the material characteristics impact seismic responses.

6. 6.

   Design a brief study plan to assess the site-specific factors impacting a proposed new bridge in a seismic zone. What steps would you include, and why?

   Hint

   Think about the questions you would need to answer for a safe and functional bridge design.
