Cold-formed steel (CFS) with several of the advantages is selected in construction activity as structural and non-structural element. CFS with variety of shape, dimension and grade is chosen to replace traditional material that largely used before. In the study, CFS is utilised as a compression member to support beams element in the building. The column made with CFS is important to sustain the load and build the stable equilibrium circumstances. The column stability is the big issue that must be discussed and determined to prevent the buckling load, unmanageable deflection and lastly building collapse. So that, the study of structural properties and column capacity under compression load of the column is being investigated. Compression test of built up CFS channel that is attached at open side facing by using bolting through the web of the channel. A tensile coupon specimen of channel is taken at the flange and web of CFS channel to find the actual material properties the results that the CFS behave similar to a carbon steel with yield stress 500 MPa. Five arrangement of bolt that are margin of its mid height, compressed using a servo machine to get the axial capacity of the column. Under constant length of 900 mm and constant material, the end distance of bolt to the tip of the column are greatly affecting the column capacity by strengthening its bearing capacity. Hence, it is recommended that, the end distance of bolt must be placed at 20 mm to improve the bearing strength of the column, and the spacing of columns can be restudy for better results.

Experiment previously showed several findings that the strength of cold-formed steel cross-section are not the same, where web strength and flange strength do not give the same response when receiving the axial load. This occurs not only because of a shift in the center point of the force due to deformation of the cross section, but also due to different strengths in cross-section, especially on the web section and flange section. To find out more details of this case, the experiment carried out the tensile test for mechanics property and compression test with an axial load to find which parts are weaknesses, then used as a reference in combining the profile. The compression test results showed significant increase in compression capability between single profile with double profile back to back (Dbb) or double profile flange to flange (Dff) with ratio 1: 2.24 and 1: 2.44 respectively. There is a non-linear increase in the value of Aeff and Ieff when becomes combine profiles (double, quadruple, hexatruple), so this can be the basis for increasing the combine profile capacity to be able to withstand larger loads. This experiment can show a basic performance of CFS, where are weak section parts of a profile can be used as a reference to put combine profile to increase compression capacity. With a numerical analysis approach compared to the experimental results, the combination of Cold-formed steel profile is established as a column for the low-rise building structure.

Abstract Strenx Section 900 is a cold-formed steel section made of hot-rolled, high-strength steel with a minimum yield strength of 900 MPa (131 ksi). Its high strength combined with naturally stiff form enables construction of stronger and lighter structures. The common shape is a U-bend channel. This datasheet provides information on composition, physical properties, tensile properties, and bend strength as well as fracture toughness. It also includes information on forming, machining, and joining. Filing Code: SA-792. Producer or source: SSAB Swedish Steel Inc..
