33.13.1. Necessity for Site-Specific Spectra

Try these first

1. 1.

   What are site-specific spectra?

   Hint

   Think about what factors might change how a building shakes during an earthquake.

2. 2.

   Why are soil conditions important in seismic assessment?

   Hint

   Consider how you might dance on a hard floor versus a soft carpet during an earthquake.

3. 3.

   Why are site-specific spectra important in structural design?

   • They are generic formats.
   • They account for local conditions.
   • They do not consider soil type.

   Hint

   Think about whether designs should be one-size-fits-all.

4. 4.

   True or False: Basin effects can decrease the seismic forces experienced by a structure.

   • True
   • False

   Hint

   Imagine how echoes in a canyon amplify sound.

5. 5.

   A city is planning to build a new hospital near a known seismic fault line. Describe how you would develop a site-specific spectrum for this project.

   Hint

   Consider how each step influences the safety and functionality of the hospital.

6. 6.

   Discuss the potential failures that could occur if a nuclear power plant relies solely on generic seismic spectra for its design.

   Hint

   Think about the importance of customizing designs for high-stakes structures.
