8.18. Experimental Methods for Measuring Harmonic Response

Try these first

1. 1.

   What is the primary purpose of shake table tests?

   Hint

   Think about what happens during an earthquake.

2. 2.

   Name one device used in modal testing.

   Hint

   Consider tools that apply sinusoidal inputs.

3. 3.

   What is the function of a shake table test?

   • To simulate harmonic excitation
   • To measure static loads
   • To assess material strength

   Hint

   Think about what happens during earthquakes.

4. 4.

   True or False: Modal testing can help identify dynamic properties of a structure.

   • True
   • False

   Hint

   This involves using sensors to get measurements.

5. 5.

   Design a small-scale shake table test for a model building to measure its response to seismic activity. Outline the key steps involved.

   Hint

   Think about how scaling down impacts the test setup.

6. 6.

   Compare the advantages and disadvantages of shake table testing versus modal testing for structural analysis.

   Hint

   Consider factors like cost, realism, and data type.
