Criterion for elastic buckling analysis. Proceedings of the 10th international conference on computational structures technology

Research output: Contribution to conferencePaper

Abstract

The objective of this study is to propose a criterion of stability capable of predicting an impending failure by elastic buckling of an element of a structure consisting of beam-column elements. In this work, the focus is on the effect of the rigidities of springs (rotational and translational), positioned at the ends of an element (beamcolumn) vis-à-vis the stability analysis. The role of the springs is to model the nodal restraints of any element of a given structure. This formulation offers significant practical advantages in the elastic buckling analysis of such structures. This approach is performed through a relationship to several parameters, such as the relative retention factors and the factor K. This relationship can be regarded as particularly reliable as justified by the good results achieved regarding the rupture of several buckling structures that were investigated. Comparison the results obtained by the current study and those from the Eurocode for calculating the effective length factor K shows a substantial difference between the two formulations, particularly in the case of non-braced structures.
