Analysis of Cable-Membrane Structures Using The Dynamic Relaxation Method

Popis výsledku v původním jazyce

This paper compares the effectiveness of different schemes of dynamic relaxation method (DRM) for the analysis of cable and membrane structures. DRM is an iterative process that is used to find static equilibrium. DRM is not used for the dynamic analysisof structures; a dynamic solution is used for a fictitious damped structure to achieve a static solution. The stability of the method depends on the fictitious variables (i.e. mass a damping) and time step. The effect of mass distribution along the structure is also studied in the paper. Eight different schemes DRM will be used in this paper. Schemes A and B are based on the theory of viscous damping. Schemes C, D and E are based on the theory of kinetic damping (KD) with a peak in the middle of the time step and schemes F, G and H are based on the theory of KD with parabolic approximation. A cable is approximated as a tension bar, a catenary (several tension bars) and a perfectly flexible element. For membrane structures a triangular
