The Structural Engineer, Volume 12, Issue 7, 1934
The CHAIRMAN (Mr. Ewart Andrews) said that he was sure all those present had enjoyed the paper, and, when they had studied it sufficiently well to understand it, they would realise that Mr. Leys had spent a great deal of time and thought in tackling this paper on the very difficult subject that the Americans, he thought, called "soil mechanics.” Mr. Leys had said in connection with one of the diagrams, that Rankine had assumed that a certain line was a straight line. The fact was that he had assumed it was a straight line because that made if easy for him to get his formula! That, indeed, was the reason for all these mathematical assumptions. If one did not make some assumption which enabled a certain simple result to be reached, then, of course, one could not get anywhere.
The CHAIRMAN (Mr. Ewart S . Andrews, BSc., M.Inst.C.E., Vice-president) proposed a very hearty vote of thanks to Mr. Roberts for the excellent material he had provided for study, and for the excellent manner in which he had described the properties of the high tensile steel dealt with.
THE most readily understood method of dealing with eccentric load (or, which is much the same thing, with bending moment) is that of the Equivalent Axial Load. By this method one takes the total actual load on the column and adds to it an amount to correspond with the bending moment. The sum is called the “total equivalent axial load,” and the column is designed upon it, without further reference to the bending moment. A.B. Dailey
