Abstract
The structural behaviour of pre-stressed cable-and-post structures has recently drawn the attention of the researchers. The aim of this paper is to focus on some practical aspects of the problem.
The investigation concentrates on the stage of the erection, especially on the stability of cable structures when subjected to no external load.
The analysis of bifurcation of equilibrium is based on the method presented here. The advantage of this method is that practical quantitative conclusions can be drawn concerning the measure of stability.
As an example, the stability of a cable structure (a modified version of the Geiger cable dome) is investigated. Critical loading conditions in the state of pre-stress are analyzed. Using a simplified procedure based on a detailed parametric study, practical conclusions are drawn for different geometric arrangements.
