Maximum Moment Of Square, Rectangular HSS And Box Shapes:
 
Calculation:
Designer/Checker:
   
Input:  
   
 
(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 F7:
This calculation applies to square and rectangular HSS, and doubly symmetric boxshaped members bent about either axis, having compact or noncompact webs and compact, noncompact or slender flanges.
Height of web (h - in or mm)
Thickness of web (tw - in or mm)
Steel yield strength (fy - ksi or MPa)
Section modulus of the beam, axis of rotation (S - in^3 or mm^3)
Plastic section modulus, axis of rotation (Z - in^3 or mm^3)
Width of flange (bf - in or mm)
Thickness of flange (tf - in or mm)
