32.6. Nonlinear Structural Response

Try these first

1. 1.

   What is material nonlinearity?

   Hint

   Think about how materials behave when subjected to high stress.

2. 2.

   What does geometric nonlinearity refer to?

   Hint

   Consider how buildings might sway during strong earthquakes.

3. 3.

   What is the primary cause of material nonlinearity?

   • Yield Stress
   • Shape Change
   • Temperature Change

   Hint

   Think of the stress-strain relationship.

4. 4.

   True or False: Hysteresis models are only applicable under linear loading.

   • True
   • False

   Hint

   Consider the purpose of hysteresis in material response.

5. 5.

   Given a structure that experiences significant yielding under seismic load, explain how you would approach modeling it using hysteresis models.

   Hint

   Reflect on the cyclic loading and look for the model that best captures real conditions.

6. 6.

   You must analyze a multi-story building with large displacements during an earthquake. How would geometric nonlinearity affect your design considerations?

   Hint

   Think about how the building's stability and safety are influenced by geometry.
