Calculation of shear and moment envelopes by Macauley's method

Abstract

The paper describes the use of a microcomputer to determine the behaviour of continuous beams. Three procedures are described: the analysis of continuous beams subject to generalized loadings using Macauley's method, the extension to include the production of influence lines, and the analysis of these influence lines to comply with a loading code. Results are presented to show how different assumptions about partial factors applied to dead loads can produce ranges of moments for which the structure must be designed. The implications for the designer of the complexities of a modern highway design code are considered in some detail, and the methods used to produce bending moment and shear force envelopes for structures designed to these rules are discussed.
