Calculation:

Designer/Checker:

Input:

Metric Units

(Note: All input Metric units are converted to English units for the equations below and then the output English units are converted back to Metric)

From AISC F9:

This calculation applies to a tee loaded in the plane of symmetry.

LRFD

Stem in tension or compression?

Stem in tension

Stem in compression

Flange is C, NC or S?

Flange in tension, or compact flange in compression

Noncompact flange in compression

Slender flange in compression

Unbraced length (Lb - ft or m)

Torsional constant (J - in^4 or mm^4)

Steel yield strength (fy - ksi or MPa)

Moment of inertia, y-axis (Iy - in^4 or mm^4)

Depth of the beam (d - in or mm)

Depth of the area in compression (y - in or mm)

Plastic section modulus, x-axis, (Zx - in^3 or mm^3)

Elastic section modulus, x-axis (Sx - in^3 or mm^3)

Moment of inertia, x-axis (Ix - in^4 or mm^4)

Thickness of web (tw - in or mm)

Width to thickness ratio of the flange (WTF = bf/2tf)

Limiting slenderness of compact flange (WTFp)

Limiting slenderness of noncompact flange (WTFr)

Output:

Maximum moment of the beam, Mu =
