• Behaviour of the unstiffened wide flanged member is not characterized by the available literature or current design standards. Torsional moment applied on the one flange unstiffened member causes the member to undergo local distortions. Conventionally, to avoid these local distortions stiffeners are provided in the joint. However, these stiffeners may add unnecessary costs to the joint and elimination of these stiffeners will lead to more economical solution. Behaviour of the unstiffened member subjected to the torsional loading has been explored in this report. Parametric numerical analysis studies have been performed to distinguish the effect of cross sectional dimension on the response of the member. Nine full-scale laboratory tests were conducted to further the existing knowledge. The response of the member has been assessed under the combined axial load and torsional moment. Studies have been conducted to provide the basis to calculate the behaviour of the unstiffened member for design.
