Description

Default

Fy

Yield strength of the section's steel

36ksi

Fu

Ultimate Tensile Strength of the section's steel

58ksi

Kx

Effective length factor for buckling about the section's strong axis

1.0

Ky

Effective length factor for buckling about the section's weak axis

1.0

Lbx

Unbraced length for bracing preventing buckling about the section's strong axis

Member’s length

Lby

Unbraced length for bracing preventing buckling about the section's weak axis

Member’s length

a

Spacing of web stiffeners. This is the spacing of any stiffeners along the web of a beam

0.0 (i.e. no stiffeners)

Flange Hole Area

Area of any bolt holes in the flanges of the section. This area will be deducted from the cross sectional area when computing tensile stress

0.0

Web Hole Area

Area of any bolt holes in the web of the section. This area will be deducted from the cross sectional area when computing tensile stress

0.0

U

Area Reduction factor. This factor is applied to the sectional area (after bolt holes have been deducted) when calculated tensile stress. You can use it to reduce the effective area by a defined amount. It must have a value between 0 and 1.0

1.0

Cb

Moment modification factor used to determine allowable compressive stresses in bending. (See ASD code for details)

1.0

Cmx

Moment reduction coefficient for bending about the section's strong axis (see ASD code)

1.0

Cmy

Moment reduction coefficient for bending about the section's weak axis (see ASD code)

1.0

Fabrication

The method by which the section was manufactured. This describes the residual stresses in the section.
