6.17. Limitations of SDOF Modeling

Try these first

1. 1.

   What does SDOF stand for?

   Hint

   It refers to a system modeled with just one motion coordinate.

2. 2.

   Name one limitation of SDOF modeling.

   Hint

   Think about complex structures during earthquakes.

3. 3.

   What is a major limitation of SDOF models?

   • They can model torsion effectively
   • They accurately represent higher modes
   • They simplify complex structures

   Hint

   Think about the focus of SDOF models.

4. 4.

   True or False: SDOF models are always sufficient for structural analysis.

   • True
   • False

   Hint

   Consider cases where more than one degree of freedom is necessary.

5. 5.

   Evaluate the effectiveness of SDOF modeling in the context of a historical structure facing modern seismic loads. What considerations for MDOF would apply?

   Hint

   Research historical building codes and their adaptations to seismic events.

6. 6.

   Consider a new architectural design for a mixed-use high-rise. Outline the steps you would take to decide between SDOF and MDOF modeling.

   Hint

   Consider structural features like asymmetry and varying stiffness.
