5.2.1. Definition

Try these first

1. 1.

   What is a dynamic degree of freedom?

   Hint

   Think about how we define movement in engineering.

2. 2.

   Can you name an example of a structure with dynamic degrees of freedom?

   Hint

   Consider structures you see every day.

3. 3.

   What defines dynamic degrees of freedom in a structure?

   • Independent coordinates
   • Fixed points
   • Structural weight

   Hint

   Think about what is needed to describe motion.

4. 4.

   True or False: A cantilever beam has multiple dynamic degrees of freedom.

   • True
   • False

   Hint

   Consider the simplicity of a cantilever beam.

5. 5.

   If a multi-story building has five floors, how many potential dynamic DOFs are there if each floor can sway independently?

   Hint

   Consider that each floor contributes to the overall movement.

6. 6.

   Discuss how the dynamic degrees of freedom change when considering a structure designed for higher seismic zones compared to standard zones.

   Hint

   Think about safety and how structures adapt to different seismic risks.
