Fully stressed suspension cable design
A numerical procedure suited to an interactive computer system is described whereby not only the analysis but also the direct design of a suspension cable linkage of varying section under constant stress may be achieved. Any combination of in-plane stati concentrated and distributed loading can be accommodated and the method takes account of self-weight, anchorage flexibilities, temperature effects as well a gross deformations. Under self-weight alone, the method readily predicts the classical form of the constant stress catenary. Only a small computer is required in which the data entry can be by interrogat on. Thence, quessed initial values as in transfer matrix methods are improved automatically by the Newton method. The significance of the technique lies in the fact that surprisingly few modifications to a gross-deformation, analysis program are required in order to produce a design program for a highly non-linear type of structure.
