The buckling of the physically nonlinear frame-rod structural systems

Abstract

Abstract The article shows that different elements of timber structural systems loose stability at different stages of their deformation. The graphs of geometrical parameters affecting the critical parameters of stability reaching have been given. The results of the stability analysis for frame-rod structural systems taking in account stress values affecting the mechanical characteristic of timber have been presented. Using comparative analysis, we have shown the loading schem affecting the critical force value and the length factor. Using numerical simulation, we have got that the stress state is significantly affected by the critical parameters of stability for the considered system.
