[Abstract] The present paper suggests the application of a non-linear model of analysis to study the final critical stage of double-Iayer space trusses. A description of the analysis techniques is proposed to take into account the resistant and geometric nonlinearity. The model developed has been applied to the study of the repercussion that the dimensioning of the members has on the stress-strain curves of the structure, as well as in the evaluation of itsbearing capability when the final limit stage is reached. In order to exemplify this, various solved cases are enclosed, corresponding to different typologies of trusses and dimensions for which different dimensioning criteria have been used. Furthermore, a new method is proposed for the dimensioning of space structures, starting from the described technique of non-linear analysis.
