This paper describes an investigation into the stability performance of a novel type of aluminium support structure for a high-energy physics experiment by utilising a series of elastic nonlinear buckling analyses, and the results are presented. Values for the maximum allowable asymmetric loading and assembly imperfection are also presented. A unified proceedure for evaluating similar structures has been developed.
