Lateral torsional stability of stud functioning as abeam, kcr;t (5.3.1 (EC5, 6.3.3))

With braced battens, the distance between lateral restraint = L/2. Due to udl loading a factor of 0.9 has been used (approximate solution)

and because loading is applied at the compression edge, 2h has been added.

Critical bending stress, am.crit am.crit = (equation (4.8); EC5, equation (6.32))

Lateral torsional buckling condition (4.5.1.2 (EC5,6.3.3)):

Relative slenderness for Xrel.m = bending, Xrel.m (equation (4.10); EC5, equation (6.30))
