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.

墙体在施工阶段基本为无墙体支撑，此时，按现行国标《冷弯薄壁型钢结构技术规程》(GB 50018-2002)规定计算是可靠、偏安全的，在计算其承载能力时应考虑单轴对称冷弯卷边槽钢截面立柱弯扭失稳，在计算立柱弯扭失稳换算长细比λ_w时，截面两端翘曲宜按不受到约束条件计算。
