What type of movement is involved in translational DOF?
💡 Hint: Consider if the motion is linear or circular.
Coupled DOFs are present when translation and rotation are:
💡 Hint: Focus on the interaction between the two types of movement.

Challenge Problems
Push your limits with advanced challenges
Design a simple structure that must account for translational, rotational, and coupled DOFs. Describe how each type of freedom will affect its response to seismic activity.
💡 Hint: Consider how seismic forces impact tall buildings and what systems are needed to stabilize them.
Evaluate a structure's performance. Given it has high torsional loads during an earthquake, discuss the implications of ignoring coupled degrees of freedom in your analysis.
💡 Hint: Think about how complex loads might interact and affect building safety.
