Impact of Dimensions of Flanges and Lips on Shear Strengths of Thin-Walled Steel Channel Sections
摘要
Thin-walled steel sections are widely utilized in construction due to their advantageous properties. From a structural perspective, these sections are designed to withstand various forces, including compression, bending, and shear, among others. While the behaviors under compression and bending are well-established within theoretical calculations, the analysis of shear resistance involves a range of different considerations and theories. Historically, shear capacities were traditionally assumed to be considered solely by webs of steel sections although the presence of the lips and flanges also significantly influences the shear strengths of these sectional types. With advancements in linear buckling analysis, the influence of these components on shear strengths of such sections is now being considered. Therefore, this paper will explore the impact of the dimensions of components such as lips and flanges on the shear capacity of cold-formed steel sections with channel shapes. The goal is to provide recommendations for optimizing the shear resistance of these sections.
