Redundancy Factor (ρ)

Plain Definition: A factor that increases seismic design forces for structures lacking load path redundancy.

Technical Description: Accounts for vulnerability in systems where lateral forces rely on few elements. Codes apply this factor to improve reliability.

Use in Design: Part of base shear calculation in modern seismic codes.
