“…W pracach [11,12] przeanalizowano utratę grubości ścianek przez cienkościenne przekroje otwarte. Wykorzystując teorię prętów cienkościennych [13], w której przekroje sprowadza się do linii środkowej można zapisać następujące wzory, według których oblicza się pole przekroju A, stałą skręcania K, momenty bezwładności Jy i Jz oraz wycinkowy moment bezwładności J:…”

The article analyzes the effects of surface atmospheric coagulation on steel elements. A brief overview of selected corroded road structures in urban infrastructure was presented. In order to carry out calculations of the bearing capacity and deformability of elements of a corroded structure, it is necessary to start from determining its corroded geometrical dimensions. The geometric characteristics of the corroded elements are changed compared to the new element. This affects the load capacity and deflection of beams.

“…The sizes P kro and M T are inserted into the interactive formula (1). Assuming different values of the eccentricity e, one can determine the values of P kr from the equation (1) according to the dependence: (8) In works [8,9] it was proved that the coordinates of points A, O after uniform corrosion of both shelves and web of this cross-section have not changed. Values of inertia moments of the cross-section decreased η -times, according to the following relationships: (9) MATEC Web of Conferences 196, 01046 (2018) https://doi.org/10.1051/matecconf/201819601046 XXVII R-S-P Seminar 2018, Theoretical Foundation of Civil Engineering…”

The paper presents the analysis of the load-bearing capacity of thin-walled steel bars such as beam-column. It was assumed that the rods are subject to uniformly distributed surface corrosion in the atmosphere over their entire length. As a result of corrosion, the mass loss of these rods, i.e. the thickness of the cross-sectional walls of the rod are evenly reduced. Therefore, the dependence of the critical force - the eccentricity changes. The theory of stability of thin-walled bars was used to calculate the load capacity of the rod. To calculate changes in the load capacity of the rod, an interactive relationship was used that combines compression with bending. A calculation example of the load capacity of an eccentrically compressed rod with a “C” section which has been corroded has been presented.
