Try these first

1. 1.

   What does UHS stand for?

   Hint

   Think about what type of hazard it assesses.

2. 2.

   What is the purpose of PSHA?

   Hint

   It evaluates earthquake likelihood.

3. 3.

   What does a UHS represent?

   • Spectral accelerations at a fixed probability
   • Maximum ground displacement
   • Earthquake frequency rates

   Hint

   Think of what spectral analysis tells engineers about safety.

4. 4.

   True or False: UHS is only applicable to high-rise buildings.

   • True
   • False

   Hint

   Consider the general principles of earthquake design.

5. 5.

   Given a set of seismic data, identify the exceedance probabilities for a UHS construction in a seismic zone and describe how it impacts design choices.

   Hint

   Look back at the UHS definition and assessment methods.

6. 6.

   Design a seismic response plan for a new infrastructure project using UHS considering various building types and locations within a city.

   Hint

   Think of the unique aspects of each building and the historical data involved.
