Question 1

What does a 2-DOF system help to analyze?

  • A single mode of vibration
  • Multiple modes of vibration
  • Only static loads

💡 Hint: Think about the various ways structures can move.

Question 2

True or False: Resonance can create unsafe conditions for buildings.

  • True
  • False

💡 Hint: Recall how swings in rhythm can lead to larger swings.

Challenge Problems

Push your limits with challenges.

Question 1

Given a 2-DOF system with masses m1 = 1000 kg, m2 = 1500 kg, and stiffness k1 = 20000 N/m, k2 = 30000 N/m, calculate the natural frequencies and describe how the results affect the design considerations of an earthquake-resistant structure.

💡 Hint: Use the formula for natural frequency based on the mode shapes and stiffness.

Question 2

How would you implement a tuned mass damper in a building modeled as a 2-DOF system? Discuss the design parameters that need to be considered.

💡 Hint: Remember that the dampers should not add excessive weight or mass to the structure.
