16.16. Limitations of Linear MDOF Models

Try these first

1. 1.

   What does it mean for a model to be linear?

   Hint

   Think about how the forces and structural responses relate.

2. 2.

   List one limitation of linear MDOF models.

   Hint

   Consider what happens to materials under extreme stress.

3. 3.

   What is one of the key limitations of linear MDOF models?

   • They assume linear response
   • They are always accurate
   • They include soil-structure interaction

   Hint

   Think about the behavior of materials under extreme load.

4. 4.

   True or False: Linear MDOF models accurately represent the behavior of materials under severe ground motion.

   • True
   • False

   Hint

   Reflect on real-world structural failures.

5. 5.

   Given that a building's design relies on a linear model, detail a scenario where this might lead to failure during an earthquake.

   Hint

   Reflect on real-world examples where buildings have failed under unexpected loads.

6. 6.

   Explain how a lack of understanding of non-classical damping could impact the safety of a high-rise structure during an earthquake.

   Hint

   Consider the role damping plays in energy dissipation.
