3 cards from this section. Quick, good the night before a test.
What does a degree of freedom (DOF) represent in structural systems?
Think about how many ways a structure can move.
How many translational DOFs does a building with three floors typically have?
Each floor typically accounts for one DOF.
What is a degree of freedom (DOF) in structural terms?
Think of how you define the position of a structure.
True or False: A building with four floors has four translational degrees of freedom.
Count the floors to find the answer.
Consider a six-story building subjected to lateral forces. Calculate the translational degrees of freedom. Discuss the impact of adding rotational DOFs for frame structures.
Count the stories first and think of the implications of rotational movements.
Evaluate the effects of neglecting rotational degrees of freedom in a newly designed sports arena and suggest a design improvement.
Consider areas in the design where rotation impacts the performance.
