"In any discussion of compression members of a structure, account has to be taken primarily of the relative "slenderness" or bending weakness of the member. If the member be so short that axial loading causes very slight deflection at any point throughout the member, it is usually designated a simple compression member and no account is taken of the additional stresses due to the deflection. When, however, the ratio of the length to the least radius of gyration of the member becomes so large that bending stresses cannot be ignored, the member is usually called a column and its consequent limiting compressive load must be smaller...The purpose of this paper is, through a series of laboratory tests, to determine both the applicability and utility of one of the more recent modes of analysis – the Theory of Limit Design – and to compare the test results with several other standard analytic column formulas" – Introduction, p. 1-2.
