The aim of this study is to present a theoretical study on the structural resistance of coldformed steel with holes. In Light Steel Framing (LSF) construction system, structural members are usually provided with holes to accommodate plumbing, electrical conduits and heating conduits. The presence of holes may reduce the ultimate strength of the frame. Therefore, the Brazilian Standard ABNT NBR 14762:2010 present the design rules in that case only for tensile frames and bolted connections. It was made a literature review on the subject, based on international standard and papers, in order to determinate the behavior of cold-formed steel with openings. The design rules of AISI S100-16 for frames with holes were presented. The results obtained based on AISI S100-16 were compared with the experimental results presented on literature review. It was presented the preliminary design abacus of the most common frames used on LSF. It was also developed a software for the design of cold-formed profiles with or without holes
