Question 1

What is the purpose of the response modification factor (R)?

  • To increase elastic demand
  • To reduce elastic demands
  • To account for wind loads

💡 Hint: Think about how structures react to seismic forces.

Question 2

True or False: Ductility factor (μ) is a measure of how much a structure can undergo inelastic deformation without failure.

  • True
  • False

💡 Hint: What happens when materials stretch?

Challenge Problems

Push your limits with challenges.

Question 1

A structure with an R factor of 5 is designed for a peak ground acceleration (PGA) of 0.4g. What would be the modified demand based on the inelastic spectrum?

💡 Hint: Remember to divide the PGA by the response modification factor.

Question 2

Consider a structure designed with a ductility factor of 3. If its elastic capacity is 0.5g, what would be the expected maximum inelastic demand?

💡 Hint: Think about how ductility allows higher deformation and energy absorption.
