14.3. Multi-Degree of Freedom Systems (MDOF)

Try these first

1. 1.

   What does MDOF stand for?

   Hint

   Think about structures with several ways to move.

2. 2.

   What does the stiffness matrix represent?

   Hint

   It relates to how much a structure resists deformation.

3. 3.

   What does MDOF stand for?

   • Multi-Degree of Freedom
   • Multi-Dimensional Forces
   • Mechanical Design of Forces

   Hint

   Think about how many ways a structure can move.

4. 4.

   The stiffness matrix K is used to determine:

   • True
   • False

   Hint

   Is stiffness related to how structures resist forces?

5. 5.

   Given a structure with a stiffness matrix K and mass matrix M, compute its natural frequencies.

   Hint

   Start with examining the properties of K and M.

6. 6.

   Discuss how different mode shapes contribute individually and collectively to seismic response.

   Hint

   Think about how individual parts of a machine work together.
