Cold-formed steels are made by rolling or pressing steel into semi-finished or finished goods at room temperatures. Cold-formed steel products are made by the working of steel billet, bar or sheet using stamping, rolling and including roll forming or presses to deform it into a usable product. Objective: By flexural-torsional behaviour channel section connected back to back. Four specimen of built up I section formed by using symmetric channel section connected back to back with the help of bolts provided in the web part of section. All the specimens were tested for flexural-torsional strength under two point loading. For this analytical study of cold-formed channel section four specimen of dimension of a 230 mm × 100 mm × 3 mm with a lip of 30 mm and 4 specimens of dimension of 180 mm x 50 mm x 1.6 mm with a lip of 20 mm and 1.8 m length were loaded vertically were unrestrained to allow flexural buckling. Method: The analytical investigation of the built up I section will be carried out using FEM modelling ANSYS. The theoretical values are calculated using IS 801:1975 and BS-5:5950. Findings: For the selected channel section with 230 mm and 180 mm depth the difference in theoretical, analytical and experimental results are found to be 2.5% and 4%. Application: Further this study can be carried out for steel section with increased or decreased depth of web and lip. It can also be used as a roofing sheet in warehouses etc.
