Warping:
(*Iwalc For the double-tee hot-rolled bar, spacing of the security bracings against the turning l1 = low =$7.1$ mm:
$W40$ = l1
(*NZabezp The member is not protected against warping.*|*Member is protected against the warping.*)
*)(*Rura For tube or box profile, spacing of the security bracings against the turning
l1 = lw =$7.1$ mm:
$W41$ = l1
(*NZabezp The member is not protected against warping.*|* Member is protected against the warping.*)
*)(*NZabezp0 The coordinate of loading applied point ao = $7.2$ cm. difference between coordinates of shearing and forcing applied point as = $7.3$ cm. Following parameters values of warping are accepted: A1 = $7.11$, A2 = $7.12$, B = $7.13$.
Ao = A1 by + A2 as = $7.11$ ×$7.14$ + $7.12$ ×$7.3$ = $7.15$
$WZ1-9$
(*Mcr Relative slenderness ratio for warping equals:
$W50$
*|*It is accepted that, the member is protected against the warping: `l L = 0.*)*)
