The paper presents an overview on research of the influence of perforations on the behavior and capacities of cold-formed steel members, with the most common channel sections. The key findings have been incorporated into American Specification with the development of the Direct Strength Method in design. The paper also introduces the application of the Direct Strength Method in previous studies on the impact of perforations on capacities of cold-formed steel channel members. The overview presented in this paper helps researchers to identify gaps for further investigation. Additionally, the obtained investigated results provide designers in better understanding the effects of perforations on the capacities of cold-formed steel channel members. It was found that there is a reduction in sectional capacities of channel sections with an increase in hole dimensions. Also, reduced hole heights and extended hole lengths are proposed to get optimal section capacities while maintaining the unchanged web hole area in general.
Key words: Review / Web holes / Strength and behavior / Cold-formed steel members
