4.2.2. Characteristics

Try these first

1. 1.

   Define dynamic excitation.

   Hint

   Think of forces that change rapidly.

2. 2.

   What role does inertia play in dynamic excitation?

   Hint

   What happens when something is moving quickly?

3. 3.

   What is dynamic excitation?

   • Forces that do not change
   • Forces that vary with time
   • A static load example

   Hint

   Consider the forces acting during an earthquake.

4. 4.

   True or False: Inertia effects are negligible during dynamic excitation.

   • True
   • False

   Hint

   Think about how a moving object behaves.

5. 5.

   A structure experiences dynamic loading during an earthquake. Describe how you would analyze the structure's response and what factors are considered.

   Hint

   Consider the methods discussed in class.

6. 6.

   Explain how resonance might affect a tall building during an earthquake and what design strategies could mitigate its effects.

   Hint

   Think about ways to reduce motion in structures.
