4.7. Earthquake as a Dynamic Excitation

Try these first

1. 1.

   What is dynamic excitation?

   Hint

   Think about forces that change over time.

2. 2.

   What does ground acceleration measure?

   Hint

   What happens to the ground during an earthquake?

3. 3.

   What type of excitation do earthquakes represent?

   • Static
   • Dynamic
   • Constant

   Hint

   Consider the nature of the forces during an earthquake.

4. 4.

   True or False: Earthquakes can be analyzed using static methods alone.

   • True
   • False

   Hint

   What happens when the ground moves suddenly?

5. 5.

   Design a building in a seismic area considering dynamic loads. Discuss the factors and design methods you would apply.

   Hint

   Factor in elements like shape, materials, and dynamic assessment methods.

6. 6.

   Evaluate a past earthquake case, identify how static designs failed and suggest improvements using modern dynamic analysis techniques.

   Hint

   Review what went wrong and what technologies could have helped.
