Bearing capacity of steel thin-walled profiles in reliability assessment

摘要: The increasing use of light steel thin-walled structures is determined by the efficiency production cold-formed profiles. However, there are problems calculating reliability structures. In particular, it necessary to specify calculation generalized bearing capacity an element from a profile. Such significantly affected initial geometric imperfections reducing its capacity. At same time influenced uneven distribution mechanical characteristics over section A paired sigma profiles with height 300 mm was taken as object study. This paper presents results effective profile operating under axial compression bending without and (additional eccentricity element’s curvatures). Besides, reveals laboratory studies properties cross after using direct indirect test methods.
