The maximum fiber stress in bending for laterally supported beams and girders is F b = 0.66F y if they are compact, except for hybrid girders and members with yield points exceeding 65 ksi (448.1 MPa). F b = 0.60F y for non-compact sections. F y is the minimum specified yield strength of the steel, ksi (MPa). Table lists values of F b for two grades of steel.
