| Title of the article | Loss of stability of sheet oblique consoles |
| Abstract. | Problem statement. The problem of estimating the bearing capacity due to the loss of stability of assemblies of metal structures in the form of thin-walled oblique corner leaves is considered. Results. A technique for calculating the stability of the edges of sheet consoles is developed taking into account geometric and physical nonlinearity. Numerical experiments were performed with varying geometric and mechanical parameters. Based on the analysis of numerical experiments, formulas were obtained for calculating the critical force. Conclusions. The significance of the results obtained for the construction industry lies in the fact that the task of determining the critical load is reduced to an analog of the Euler formula, but with a correction coefficient that depends on the geometric parameters of the oblique angle plate. Based on the results of numerical experiments, it is possible to obtain a single regression function for calculating the critical force, where the correction factor depends both on the slant angle of the plate and on the relative length. It was found that the correction factor is almost independent of the thickness of the plate and the Poisson ratio. |
