It is presented experimental study on shear behavior of diaphragm assembly using V-840 profiled steel sheet.It is also compared the different effect of the stressed diaphragm action with purlins and without purlins and the experimental result indicates that the edge member and sufficient fastenings are vital to the stressed diaphragm action to work.It is acceptable to use the BS code of stressed diaphragm to design as compared with experimental results.
