Fracture-Critical Members of ASTM A709 steel plates: Tensile members that are primarily load-bearing or have flexural components whose failure would be expected to result in failure of the structural member or bridge without overloading.
Main load-carrying members of ASTM A709 steel plates: steel members bearing main design loads, including static loads, dynamic loads, impact loads and other loads.
Non-Fracture-Critical Members of ASTM A709 steel plates: Tensile members that are primarily load-bearing or have flexural components, the failure of which is not expected to result in failure of structural members or failure of bridges that are not overloaded.
Non-tensile member of ASTM A709 steel plates: any steel member not subjected to tensile stress under any design load.
Auxiliary components of ASTM A709 steel plates: steel components that locate and support the main load-bearing components, or connecting parts, signs or other auxiliary facilities, but do not directly bear the main design load..
Tensile member of ASTM A709 steel plates: A part or component of a fracture-critical (F) or non-fracture-critical member (T) that is subjected to tensile stresses at various design loads.
