Question 1

What do Degrees of Freedom (DOF) refer to?

  • The number of possible structural movements
  • The number of floors in a building
  • The total mass of a structure

💡 Hint: Think about how a structure can move.

Question 2

True or False: Increasing the number of DOF simplifies the structural analysis.

  • True
  • False

💡 Hint: Consider how much more effort it takes with more movements.

Challenge Problems

Push your limits with challenges.

Question 1

A multi-story building has been modeled with 12 DOFs. If during a seismic analysis it was found that the first two modes account for 80% of the response, is it reasonable to consider it a single-degree-of-freedom system for certain analyses? Justify your answer.

💡 Hint: Consider the concept of mass participation in SDOF.

Question 2

Explain the impact of ignoring rotational degrees of freedom in an asymmetric structure during seismic analysis.

💡 Hint: Think about how torsion complements translation in buildings.
