In order to efficiently design a battened strut under an eccentrically applied load, its two main members can be chosen to have different properties of cross section. This paper presents a theoretical analysis for the determination of the critical load of
such unsymmetrical battened struts under axial as well as eccentric loads. An expression is deduced for the direct determination of this critical load which, when inserted in one of the approved design formulae, will give the required failure load.
The analysis showed that the critical load of battened struts, different from solid struts depend on the eccentricity of loading. Comparison with existing experimental data is found to be satisfactory.
