27.11.2. Northridge Earthquake (1994)

Try these first

1. 1.

   What year did the Northridge Earthquake occur?

   Hint

   Look for significant historical earthquakes in the early 1990s.

2. 2.

   Why are building codes important after an earthquake?

   Hint

   Consider the role of codes in construction safety.

3. 3.

   When did the Northridge Earthquake occur?

   • 1994
   • 1989
   • 2000

   Hint

   Think back to the early 1990s.

4. 4.

   True or False: The Northridge Earthquake revealed the significance of vertical accelerations.

   • True
   • False

   Hint

   Consider what characteristics of the earthquake were significant.

5. 5.

   Analyze the potential hazards that vertical acceleration poses to older structures built pre-1994. What strategies could mitigate these risks?

   Hint

   Consider historical earthquake responses and methods to improve resilience.

6. 6.

   Using the lessons learned from the Northridge Earthquake, propose a design concept for a new high-rise building in a seismic zone. Outline key features.

   Hint

   Think about modern engineering practices in earthquake resilience.
