Abstract:

Cold-Formed Steel (CFS) is offered in different sizes, shapes, and dimensions using rolling, bending, and pressing equipment and has been established as a non-structural and structural component for building. Due to its numerous advantages, CFS is studied to propose as a structural component for buildings, which needs to be improved to minimize the structural integrity issue, especially buckling, and maximize stability. An example of the improvement for the CFS section is producing the section to develop a basic CFS built-up section, either in a face-to-face arrangement or back-to-back arrangement, by utilizing a fastener. The fastener, especially the self-drilling screw, is used for forming the CFS built-up back-to-back (CFSBB) column with two considerations, including end spacing and middle spacing. The primary purpose of the study is to ascertain the mechanical properties of self-drilling screw configuration for CFSBB columns by using experimental activity. The self-drilling screw was placed on the CFSBB column in five different configurations. One configuration used only two screws in one row, while the other configuration used four screws in two rows. The CFSBB column was connected to every row with two screws and in different directions. Then, the column was tested using an automatic compression machine under semi-rigid support conditions. The failure shape of the column was observed and recorded. From the experimental result data, the highest ultimate load and compressive strength value of the CFSBB column were at the location of the end spacing of 100 mm and middle spacing of 50 mm.
