33.3.2. Family of Response Spectra

Try these first

1. 1.

   What is a response spectrum?

   Hint

   Think about what peak responses indicate.

2. 2.

   What happens to spectral ordinates as damping increases?

   Hint

   Higher damping means less motion, remember?

3. 3.

   What is a family of response spectra used for?

   • To identify total energy consumption
   • To assess structural responses under different damping ratios
   • To analyze thermal performance

   Hint

   Focus on the relationship between damping and structural response.

4. 4.

   True or False: Higher damping leads to higher spectral ordinates.

   • True
   • False

   Hint

   Think about what damping achieves in structural behavior.

5. 5.

   A structure is designed with a damping ratio of 10%. Evaluate how this choice impacts its performance in a seismic event compared to a structure with 2% damping.

   Hint

   Focus on the relationship between damping and peak load capacities.

6. 6.

   Consider a scenario where you need to design a bridge with varying damping ratios between 2% and 10%. Analyze how this range affects your response spectrum and the resultant design choices.

   Hint

   Assess the importance of reducing forces through proper damping.
