Experimental Study on the Behaviour of Intermediate Length Web Stiffened Cold-Formed Steel Columns with Perforated Spacers

The present work describes the study on the Experimental investigation on the web stiffened intermediate length cold form steel column with perforated spacers under axial compression. In this work the failure modes and ultimate loads are analysed by using perforated spacers at different intervals. Two types of sections are consi dered for this study. Fourteen columns are experimented out of which, one column from each type is control specimen and others are by providing with one, two and three spacers having width of 50 mm & 20 mm. The section properties and length of the columns are predicted by performing elastic buckling analysis using CUFSM software.The column strength obtained by the Experimental analysis are presented and discussed.
