Elastic vs. Inelastic Response


  • The red line shows the force and displacement that would be reached if the structure responded elastically.
  • The green line shows the actual force vs. displacement response of the structure
  • The pink line indicates the minimum strength required to hold everything together during inelastic behavior
  • The blue line is the force level that we design for.
  • We rely on the ductility of the system to prevent collapse.
