36.6. Comparison with Code-Based Spectra

Try these first

1. 1.

   What is the main purpose of comparing site-specific spectra with code-based spectra?

   Hint

   Think about the importance of location in architecture.

2. 2.

   What effect do soft soils typically have on seismic response?

   Hint

   Recall the relationship between soil type and building safety.

3. 3.

   What is a significant outcome of comparing site-specific response spectra with code-based design spectra?

   • Increased costs
   • Improved building performance
   • More complex analyses

   Hint

   Consider the benefits to structural integrity.

4. 4.

   True or False: Site-specific spectra generally reduce the understanding of seismic responses for engineers.

   • True
   • False

   Hint

   Remember the objective of site-specific analysis.

5. 5.

   Consider a structure in a soft soil area compared to one on hard rock. Discuss how the proposed designs might differ in terms of materials and structural integrity.

   Hint

   Focus on how soil type influences the design.

6. 6.

   A building's original code-based design was based on IS 1893. If site-specific analysis shows significant amplifications at low frequencies, what design alterations should be considered?

   Hint

   Reflect on how to ensure stability against amplified forces.
