本文介绍了北美冷弯薄壁型钢结构规范NAS S100中最近表决通过的直接强度法(DSM)的抗剪设计方法。该方法需要计算完整截面的剪切屈曲荷载Vcr。给出了用半解析法和样条有限条屈曲分析计算纯剪作用下槽形截面剪切屈曲的算例。文中还介绍了最近关于带矩形和三角形腹板加劲肋的纯剪槽钢截面屈曲和强度的研究工作。
The paper describes the recently balloted Direct Strength Method (DSM) of design for shear of the North American Specification for Cold-Formed Steel Structural Members NAS S100. The method requires the shear buckling loadVcrof the complete section to be computed. Shear buckling examples of channel sections in pure shear using both the semi-analytical and spline finite strip buckling analyses are presented. Recent work on the buckling and strength of channel sections in pure shear with rectangular and triangular web stiffeners is also described.
