: Load Modifier (account for ductility, redundancy, and operational importance). γigamma sub i : Load Factors (increase the estimated load). Qicap Q sub i : Load Effects (dead load, live load, wind, etc.). : Resistance Factors (decrease the nominal strength). Rncap R sub n
= Statistically derived load factor applied to specific force effects. Q_i = Force effect (moment, shear, axial load). = Resistance factor applied to nominal material strength. R_n = Nominal resistance of the structural element. Core Structure of the 5th Edition Specifications : Load Modifier (account for ductility, redundancy, and
Fracture-critical member (FCM) guidelines, requiring mandatory non-destructive testing for components whose failure could cause a total bridge collapse. 3. Strength Limit State : Resistance Factors (decrease the nominal strength)
When inspecting or rehabilitating a bridge designed around 2010, engineers must refer to the specifications in place at the time of construction to accurately calculate its current capacity. = Resistance factor applied to nominal material strength
