An experimental study on distortional buckling strength of the cold formed steel columns with inward lip
Keywords:
strength, forming, cold working, strength of materialAbstract
The aim of this study is the distortional buckling strength of open thin walled cold formed steel column with inward lip under axially compression with hinged end condition. This study gives a very wide knowledge about the cold formed steel necessity & its requirement in various applications in different fields. It also gives the knowledge about the various modes of failures of cold formed steel members, like local buckling, distortional buckling and flexural - torsional buckling. To study the distortional buckling of the open thin walled section, the section made partially closed by providing spacers which connects the lip of open section at different intervals. Four specimens were fabricated with the uniform thickness of 1.6 mm having a yield stress of 350 Mpa. One control specimen i.e. without spacers and other three specimens with spacers by varying the numbers were tested. The spacers are connected to the column by self-tapping screws.
