30.17.3. Spectral Matching

Try these first

1. 1.

   What is spectral matching?

   Hint

   Think about matching ground motions with a target.

2. 2.

   Why is spectral acceleration important?

   Hint

   Consider structural responses during earthquakes.

3. 3.

   What does spectral matching aim to achieve?

   • A. Create random ground motions
   • B. Align artificial ground motions with a target spectral curve
   • C. Simplify analysis methods

   Hint

   Think about why engineers want precise matches for analysis.

4. 4.

   Is spectral acceleration important for nonlinear time-history analysis?

   • True
   • False

   Hint

   Consider how analyses depend on accurate inputs.

5. 5.

   Given a spectral acceleration curve for a site, propose a method for generating ground motions that align with it. Describe your approach in detail.

   Hint

   Think about both existing data and mathematical functions.

6. 6.

   Critically evaluate a proposed spectral matching technique and consider its limitations in real-world applications.

   Hint

   Examine the basis of the method and its real-world implications.
