The computer modeling and analysis of cable structures creates a major problem for the analyst in that the geometry of the cables is dependent on analysis results. The purpose of this paper is to describe a general purpose procedure for the nonlinear static analysis of cable structures which is implemented as part of the GTSTRUDL computer program for structural analysis and design. The procedure addresses the modeling problem as well as the nonlinear stress analysis task by incorporating the use of a family of isoparametric one-dimensional cable elements in conjunction with a two-phase analysis algorithm. An example illustrates the method.
