The thesis describes the derivation and uses of a simple function, "The Bending Efficiency Factor", which may be used to examine the performance of cross-sectional shapes in bending. The function yields a value for efficiency which is independent of the overall dimensions of the cross-section, providing a measure of the effectiveness for the distribution of material within beam cross-sections. The Bending Efficiency Factor is used to investigate the performance of steel I-sections in bending, this is achieved by considering the variation of bending efficiency with change in cross-sectional shape, the information is displayed graphically in the form of efficiency surfaces. It is shown how the constraints imposed by the methods of production and design codes of practice can be used to form boundaries to the efficiency surfaces. The combination of the idea of bending efficiency surfaces and the boundaries formed by the constraints is shown to provide the basis of a simple procedure for the design of structural steel cross-sections for optimum bending strength.
