Along with the development of the construction world in Indonesia, the use of cold-formed steel (CFS) as a construction material is also increasing. The connection is an important element that must be considered in this type of material. Structural elements that are joined experience stress concentration around the hole resulting in a change of the behavior of structure that becomes more complex. To predict the failure mode of the connection section, this study conducted an experimental test to study the capacity of cold-formed steel against tensile loads. The test specimens used in this study are canal type, which is usually used as material construction, with three different configurations of screw positions. The effect of the screw will be compared with an original model without a screw. In addition, numerical simulation by ABAQUS Student Edition and analytical studies by SNI 7971:2013 which referred to AS/NZS 4600:2005 have been conducted to investigate the axial capacity of the CFS element. From the experimental results, the main failure modes for all types of screw connections are categorized by tilting and pull-out failure. Increasing space between screws will also increase the maximum load by 6.67% and 10.81% for connection with three and four screws, respectively. In addition, the specimens with one and four screw connections have an average extension which was 300% larger than that of without screw. © 2022 Int. J. of GEOMATE. All Rights Reserved.
