چکیده

The static analysis of guyed towers is very complex because of high degree of non-linearity they exhibit due to their slender and flexibility. In the static analysis of cable systems, due to the effects of nonlinearity of loading and large functions, the interference of loads and displacement have no much value. Because of having no analytical solution for these systems, numerical methods have been applied. Finite difference method (FDM) is one of the known methods which are directly related to nonlinear relative equations and, the cable system is defined using calculating of them and deformation equations . In this research, the non-linear analysis of cables under three dimension static loads is analyses using FDM. This model can be analyzed three dimension response of cable using sequential method. In this model, long and inclined pre-tensioned cables have been studied in which only axial stiffness of cable is considered while bending and torsion stiffness are assumed to be negligible.
