本文研究了应力梯度对建筑中支承墙板或屋面的冷弯薄壁型钢变形屈曲弹性临界应力的影响。利用Li和Chen最近提出的模型，计算了均布横向荷载作用下冷弯薄壁型钢梁变形屈曲的临界应力。本文研究的断面包括航道断面、ZED断面和西格玛断面。数值算例着重分析了应力梯度、截面尺寸和板材侧向约束对变形屈曲临界应力的影响。
This paper presents an investigation on the influence of stress gradient on the elastic critical stress of distortional buckling of cold-formed steel sections supporting wall sheeting or roof cladding in buildings. The critical stress of distortional buckling of cold-formed steel section beams subjected to a uniformly distributed transverse loading is calculated using the model proposed recently by Li and Chen. The sections investigated in the paper include channel, zed, and sigma sections. Numerical examples are provided that highlight the influence of stress gradient, section dimensions, and sheeting lateral restraints on the critical stress of distortional buckling.
