Corner radius effect in the thin-walled columns of regular polygon cross-section on the local buckling and load carrying capacity

Abstract

Authors of this work have been investigated a corner radius effect on the local buckling of thin-walled structures. For each considered regular cross-section shapes (i.e. triangular, square, regular pentagon or hexagon) different values of corner radii were applied taking into account a constant area of a column crosssection. This study appears to be some kind of an optimizing analysis of thinwalled members without fundamental formulation.
