30.11. Site-Specific Response Spectra

Try these first

1. 1.

   What is the purpose of a geotechnical investigation?

   Hint

   Think about what soil information is needed for earthquake safety.

2. 2.

   Why is ground motion selection important?

   Hint

   Consider how local earthquakes can differ between regions.

3. 3.

   What is the main purpose of site-specific response spectra?

   • To provide general design guidelines
   • To tailor seismic responses for critical structures
   • To analyze historical earthquakes

   Hint

   Consider the critical nature of facilities like hospitals.

4. 4.

   True or False: Ground motion selection only involves picking random earthquake records.

   • True
   • False

   Hint

   Think about how one would accurately describe local earthquake potential.

5. 5.

   Consider a new hospital being built in a region with diverse soil types. Outline the steps for developing site-specific response spectra for the facility.

   Hint

   Think about what data each step needs to ensure a solid approach.

6. 6.

   Evaluate the potential inaccuracies that might arise if a general response spectrum is used instead of a site-specific spectrum for a critical structure.

   Hint

   Consider how local conditions can drastically affect performance.
