The application of elastic catenary functions to the analysis of suspended cable structures

In a number of structural engineering applications use is made of high tensile steel cables for load carrying purposes, e.g. suspension bridges, guyed masts, overhead electric lines and cableways. In many of these applications the cable is uniformly loaded and hence hangs in a catenary. When a structure incorporating one of these elements has to be analysed difficulties are encountered due to the non-linear response of a catenary to applied loading. This paper gives graphical and analytical data together with the linearized stiffness matrix for a catenary element which enable speedy calculations to be made. The application of this to the analysis of an electric line river crossing is given. T. J. POSKITT
