Keywords: cable structures, nonlinear analysis, dynamic relaxation, kinetic damping.

Summary

Several different schemes of the dynamic relaxation method are compared in this paper. Methods with viscous damping and methods with kinetic damping are used. Kinetic damping with a peak in the middle of the time step and the kinetic damping with the parabolic approximation of the peak is used. Three-dimensional examples of cable structures are solved and the efficiency and stability of each method is compared. Three different ways of cable approximation are used. The cable is approximated as a tension bar, a catenary or a parabolic cable element. The effect of mass distribution throughout the structure is also studied.

Nine different schemes of the dynamic relaxation method are used in this paper. It is shown that it is very effective to use the kinetic damping with a peak in the middle of the time step and the uniform mass discretization for the whole structure.
