5.1. Degrees of Freedom (DOF)

Try these first

1. 1.

   What is the definition of Degrees of Freedom (DOF)?

   Hint

   Think about how many ways a structure can move.

2. 2.

   List the two primary types of Degrees of Freedom.

   Hint

   Consider movement along axes and around axes.

3. 3.

   What does Degrees of Freedom (DOF) refer to in structural analysis?

   • Minimum number of forces
   • Minimum number of coordinates needed
   • Minimum number of structural elements

   Hint

   Focus on understanding how we describe motion.

4. 4.

   True or False: Rotational DOFs only apply to structures that twist.

   • True
   • False

   Hint

   Think about rotation in general.

5. 5.

   Consider a multi-story building with irregular shapes. Discuss the factors you would consider to determine its Degrees of Freedom.

   Hint

   Think about how each floor may behave differently.

6. 6.

   Explain how the coupling of DOFs could influence the design of a multi-storey building in an earthquake-prone area.

   Hint

   Consider structural integrity and stability.
