3.10. Experimental Evaluation of Damping in Structures

Try these first

1. 1.

   What is the main purpose of shake table tests?

   Hint

   Think about what scenario shake tables are designed to replicate.

2. 2.

   Define ambient vibration testing.

   Hint

   Consider what makes it 'non-intrusive'.

3. 3.

   What is the main function of shake table tests in structural evaluation?

   • Validate material properties
   • Mimic seismic activity
   • Test for wind resistance

   Hint

   Remember, these tests help us understand vibrations.

4. 4.

   True or False: Ambient Vibration Testing involves applying an external load to a structure.

   • True
   • False

   Hint

   Think about what makes this method different.

5. 5.

   A shake table test showed that a building swayed excessively under certain frequencies. How might you adjust the design based on this result?

   Hint

   Consider how tuning a string can alter sound production.

6. 6.

   Discuss how ambient vibration testing could benefit a pre-existing structure intended for public use.

   Hint

   Think about safety measures for structures still in function.
