Challenge Problems
Push your limits with advanced challenges
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.
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.
