15.10. Use in Structural Control and Retrofitting

Try these first

1. 1.

   What is a mode shape?

   Hint

   Recall that mode shapes describe a structure's behavior under free vibrations.

2. 2.

   What does a Tuned Mass Damper do?

   Hint

   Think of it like a shock absorber.

3. 3.

   What does a mode shape represent in structural engineering?

   • A vibration frequency
   • A deformation pattern
   • A construction material

   Hint

   Focus on its definition.

4. 4.

   True or False: Base isolation allows a building to move independently of ground motion.

   • True
   • False

   Hint

   Remember how isolation works.

5. 5.

   Evaluate how incorporating a tuned mass damper in a high-rise building would impact its fundamental frequency and mode shapes.

   Hint

   Think about how the mass and position of the TMD interact with the building's structure.

6. 6.

   Given a building with weak stories, design a retrofitting approach that highlights the changes in mode shapes.

   Hint

   Consider practical retrofitting methods used in real-world applications.
