Title: | Design of columns in terms of stability | Authors: | Đelošević, Mirko Vukajlov, Ljiljana Tepić, Goran Milinković, Aleksandra Brkljač, Dijana |

In this paper, we investigate global and local stability of columns with an open and a closed thin-walled cross section. The proposed model of global stability is made of two deformable elements connected with an elastic joint. Stiffness of the elastic joint represents local discontinuity of the cross section of the column caused by the loss of stability of individual plates. The model of local stability of the columns is conceptualized on the principle of continuity of individual plates of the cross section. The coefficients of local buckling are defined as geometric parameters of the column with a rectangular hollow section (RHS) and a U-shaped cross section. The dominant parameters that influence the interactive behaviour of local and global buckling are the slenderness of plates and the column as a whole. The basic function of the developed models is to identify the stability mechanism in terms of better estimation of the critical force and higher load capacity. | URI: | https://open.uns.ac.rs/handle/123456789/1931 | ISSN: | 13331124 | DOI: | 10.21278/TOF.42204 |
