Some aspects of the stic system stability calculation

Abstract

The problem presented in this paper has been treated intensively by various researchers. However, considering that by its nature the problem of structure stability belongs to the area of nonlinear analysis, it represents an inexhaustible source for investigations. Thus, we propose a simple method to determine the elements of geometrical matrix of member rigidity by energetic method through finite element method.
