Abstract
Subject of this paper is numerical modelling of steel assembling bolt connections of CHS (circular hollow sections) or L-profiles respectively in the FEM software ANSYS 12.0 and their subsequent comparison with performed laboratory experiments. Non-linear calculations with both plastic behavior of materials and influence of large deformations were taken into account. Comparison of results, in the form of load-deformation curves, showed that numerical models describe the basic behavior of those joints. The direct numerical model outputs were modified. This modification was made with respect to real laboratory conditions taking into account the effect of the trial press machine slip stiffness and the initial slip.
