EXPERIMENTAL INVESTIGATION ON BEHAVIOUR OF COLD FORMED STEEL BATTEN COLUMN WITH ANGLES UNDER AXIAL COMPRESSION

This paper presents the study on cold formed steel built-up battened Columns. CFS are highly advantageous when compared with the hot rolled section, it has comparable load carrying capacity and durability but still the usage of cold formed steels are not so high in practice. This study deals with the cold formed steels built up batten columns formed by using 4 cold formed angles fabricated from the cold formed thin sheets and all the angles are interconnected by batten plates of 2mm thick. According to the research it has been stated that the ultimate load carrying capacity of column increases with decrease in its slenderness ratio. In this investigation four angle sections (50x50x2) are connected with batten plates and the tests are carried out by varying its angle spacing only. The theoretical and experimental analysis was carried out for the proposed section to know the ultimate load carrying capacity and the results were compared
