Abstract: Presented in this paper is an outcome of a study to assess the effect of section loss in the form of longitudinal notches on the buckling load of hollow square section steel columns. The theoretical study includes buckling load estimates based on both an iterative equilibrium as well as a non-iterative energy approach. Buckling loads based on sample laboratory experiments are also presented. The study shows that the presence of a notch can significantly reduce the axial load-carrying capacity of a steel column.
