I = Second Moment of inertia of panel profile (mm/m)
Pw = Crushing strength of the web at a support point
(kN/m)
Py = shear capacity of a web (kN/m)
-M = Moment capacity of the section, bending with
tension at top (kNm/m)
+M = Moment capacity of the section, tension at
bottom (kNm/m)
Notes
Properties calculated in accordance with BS 5950 :
Pat 6 : 1995
Design strength Py = 512 MPa for thickness up to
1mm, 350 MPa for 1.2mm
* Web crushing strength is based on support width of
50mm
* Web Crushing strength is for an external support,
double the value for an internal support.
