Question 1

What happens to the spectral ordinates as the damping ratio increases?

  • They increase
  • They decrease
  • They remain constant

💡 Hint: Consider the effect of damping on energy dissipation.

Question 2

True or False: A family of response spectra can help assess the influence of damping on structural response.

  • True
  • False

💡 Hint: Reflect on the purpose of creating multiple spectra.

Challenge Problems

Push your limits with challenges.

Question 1

A structure's response is evaluated at two damping ratios: 5% and 15%. Calculate the expected change in peak response during seismic loading and discuss how this affects design choices.

💡 Hint: Think about how much energy is dissipated in both cases.

Question 2

Develop a response spectrum curve for a building designed with damping ratios of 2%, 5%, and 10%. Discuss how each response impacts the structural design.

💡 Hint: Use numerical integration methods to plot the spectral ordinates for each damping ratio.
