“…In terms of tolerance values, the maximum measured imperfection of the webs was smaller than the maximum tolerated value, given in the standard EN 1090-2+A1, as b/50. Although this condition has been met, the results revealed a serious effect of initial imperfections, [5].…”

“…The resistive strain-gauges and inductive sensors were connected to the computer for direct evaluation. The loading process of each member was regulated close to its real behavior, measured strains ε and deflections w. The test continued until total failure, defined by the beginning of continuous increasing strains ε and displacements of the webs w. The final buckling shapes after test finishing were also revealed, [5]. Example of the test completion and overall failure of the test member B22 are illustrated in Fig.…”

The paper presents fundamental information about experimental-theoretical research oriented to determinate the resistance of thin-walled compressed steel members. The investigated members had closed cross-sections made from homogeneous materials. The theoretical analysis in this research is oriented to determinate the resistance of mentioned members according to relevant standards, while the experimental investigation is to verify the theoretical results and to investigate the behavior of mentioned members during the loading process.

“…The numerical analysis has been oriented towards the investigation and modelling of initial imperfections, caused by production processes, on the loadbearing capacities of the mentioned members. This analysis was based on the modelling of actually measured initial imperfections as spatial areas, also on the 3D simulation of the experimental tests with non-linear calculation procedures using software ANSYS based on the FEM, [3]. The results are very extensive; therefore the paper deals only with Cross-sectional group B2, Table 1 and Figure 1.…”

Abstract. Part 1 of the paper presents fundamental information about the experimental and theoretical research oriented to determine the resistance of thin-walled cold-formed compressed steel members with closed cross-sections, [1]. The investigated members were made from homogeneous material. The theoretical analysis was oriented to determine the resistance of mentioned members according to European and Slovak standards, while the experimental investigation was to verify the theoretical results and to investigate the behavior of the above-mentioned members during the loading process, [2]. Part 2 is focused on the numerical analysis of the achieved results, as well as on 3D modeling and simulation of the experimental tests.
