28.13.2. Zonation and Design Spectra

Try these first

1. 1.

   What are seismic zones?

   Hint

   Think about how earthquakes are categorized.

2. 2.

   What is the range of seismic zones in India?

   Hint

   Recall the highest and lowest zones.

3. 3.

   What is the highest seismic zone in India?

   • Zone II
   • Zone III
   • Zone V

   Hint

   Think about which zone indicates the strongest earthquakes.

4. 4.

   True or False: Design spectra are derived solely from building codes.

   • True
   • False

   Hint

   Remember what models contribute to this aspect.

5. 5.

   A new hospital is to be built in a Zone V area. Develop a basic plan on how the design spectra could guide its structural reinforcement.

   Hint

   Relate your design back to the ground shaking intensity information.

6. 6.

   Analyze the potential ramifications if engineers ignore the seismic zoning when constructing infrastructure in a major urban area.

   Hint

   Think about safety, costs, and long-term impacts on the community.
