Load Modifiers
ηD: a factor relating to ductility, as specified in AASHTO Article 1.3.3
ηR: a factor relating to redundancy, as specified in AASHTO Article 1.3.4
ηI: a factor relating to operational classification, as specified in AASHTO Article 1.3.5
The combined loads are multiplied by ηi=ηD*ηR*ηI (load modifier: a factor relating to ductility, redundancy, and operational classification). According to AASHTO 1.3.2.1-2, ηD*ηR*ηI should be greater than or equal to 0.95.
