Steel structures are traditionally designed neglecting the in-plane bearing capacity of the cladding. However, the cladding can act in coordination with the main structure, behaving as a diaphragm and contributing to its spatial stability, enabling the so-called stressed skin concept design. The subject of this paper was an analysis of behaviour of a sample steel frame cladded with corrugated sheet metal, and connected to each other by self-tapping screws. Various conditions regarding the set and the number of fastening devices, as well as method of numerical modelling of fasteners, type of the corrugated sheet metal, and overall dimensions of the frame were analysed using FEM and ANSYS workbench software, including geometric and material nonlinearity. Results can serve as useful and reliable design guidelines, and as an argument for further propagation of the stressed skin concept design as a rational design approach for steel structures.

传统上，钢结构的设计忽略了包层的平面内承载力。但是，包层可以与主体结构配合使用，表现为隔膜，并有助于其空间稳定性，从而可以进行所谓的“压力蒙皮”概念设计。本文的主题是对示例钢框架的行为进行分析，该钢框架包覆有波纹金属板并通过自攻螺钉相互连接。使用FEM和ANSYS工作台软件分析了有关固定装置的数量和数量的各种条件，以及紧固件的数值建模方法，波纹金属板的类型和框架的整体尺寸的各种条件，包括几何和材料非线性。结果可以用作有用和可靠的设计指南，也可以作为钢结构的合理设计方法，进一步推广受应力蒙皮概念设计。
