Abstract

The cable structures are long tension structures. The main aim of this paper is to provide a new efficient method in all aspects of analysis of tension structures. Tension structures belong to high- nonlinearity structures. The approach of the proposed method is based on the principle of conservation of energy. In this paper a theory for nonlinear dynamics response analysis of tension structure is based on the minimization of the total potential dynamic work developed.

Key words: Fletcher- Reeves method, optimization of energy, finite element method, perturbation technique, analyzing modal, nonlinear dynamic response.
