http://www.labciv.eng.uerj.br/pgeciv/files/Torsion%20Properties.pdf WebH is the warping constant. For bi-symmetric cru-ciform sections such as in Figures 1 and 2, this is the sum of the warping constants, H, for the two component sections. H for a plain cruciform is very small, so it is recommended that H is taken as zero. The formula for members with no warping stiffness (such as a plain cruciform) reduces to: p ...
