The wall has no support during the construction stage and the calculationbased on the national standard GB 50018-2002 (Technical code of cold-formedthin-wall steel, structures) should be reliable and safe. The crankle destabilizationof the studs with cold-formed channel section should be taken into account whencalculating the load-carrying capacity. The warpings at both ends of the sectionshould be calculated without any constraint when converting the crankledestabilization into the slenderness rationλ_w.
