The material used would be only one factor in designing this type member.
RE: fracture critical steel
Fracture-critical members — members or portions of members, including attachments, in a single
load path structure that are subject to tensile stress and the failure of which can lead to collapse of the
structure.

10.4.2 Structural steel
Structural steel shall conform to CSA G40.21. The modulus of elasticity of structural steel, Es , shall be taken
as 200 000 MPa and the shear modulus of elasticity of structural steel, Gs, shall be taken as 77 000 MPa.
Weathering steel members shall be of Type A atmospheric corrosion-resistant steel as specified in
CSA G40.21.
Fracture-critical members and primary tension members shall be of type AT, type WT, or type QT steels
as specified in CSA G40.21.
