【 摘 要 】

The paper shows the indentification of deformational-stress state of partially loaded plates composed of two elements of different thicknesses. We analyzed metallurgical processes that characterize the technology of welding steel structures. The mathematical interpretation of the local stress state, through the developed software, enables an optimal design of geometric parameters of plate or supporting elements of construction according to the stress criteria. Comparative analysis of deflection and equivalent stress obtained by the analytical method and Finite elements method (FEM), using ANSYS 12 software package, the high agreement of results in terms of values and distribution trends is noticed. The application of the results of this paper is particularly important for the optimal design of steel girders.
