Presuming acquaintance with conventional knowledge and methods used in column design, the author attempts to throw new light on the subject by using a generalisation, set down as a General Theorem, as follows:-
"Any column, however loaded, supported, and restrained, may be considered as initially bent to the shape of the diagram of applied bending moment, however caused, and to the scale determined by the axial load."
This is simple yet provides a method of solution for every case to an accuracy well within engineering limits. By its use previously established mathematical analyses are linked up with practical reasoning, the application and relative merits of approximations are made evident, and the correlation of standard deductions established.
Various primary assumptions and apparently differing curves are shown to be essentially variations of the one type. The methods of the author's previous papers, listed below, prove trustworthy, but some details are brought up-to-date. For example, a complete demonstration has been given of the important case where a column assumed uniform is subjected to a definite external bending moment as well as a longitudinal load. Again, the general curves and formula for all types of eccentric loading on the uniform column are recorded.
Various design formulae, including the latest of the British Standards Institution, and those of the Standards Association of Australia, are examined in the light of the method propounded. Certain anomalies are indicated and amendments suggested.
No one formula is practicable for all cases in design, but the procedure to obtain the requisite curves or equivalents is demonstrated.
