“…A previous article [27] focused on the selection of an appropriate method for numerical modelling of a specific joint, and the following research included attempts to deepen the knowledge of the joint's behaviour through analysis, which allowed for a wider application of clinch connections. The numerical modelling outputs enable the improvement of the manual assessment procedures and specifications of factors determining the correct assessment of the joints.…”

“…According to the steel manufacturer's certificate, the Poisson's constant was 0.3. The parameters of the supplied steel have been checked, and their results have been published, for example, in [17,27]. Testing was conducted on standard bodies designed for tensile tests (see Figure 3).…”

“…The thickness of the basic material is 2.67 mm. Clinch joint geometry is formed according to the cross-section of several samples before testing, and their confrontation with numerical model results in LS-DYNA [27]. The computing model was prepared in an ANSYS system corresponding to a full scale of the physical experiment.…”

The high energy intensity of industry and the importance of natural resources are currently much-discussed topics. Light steel structures made from thin-walled cold-formed (TWCF) profiles play an important role in this discussion because their increased use has significantly reduced the consumption of conventional structural steel. New, more efficient technologies for connections of the TWCF structures, such as punch riveting and clinching, are being developed, which are advantageous in terms of cost and time. An innovative way to obtain the physical properties of a clinch joint and instructions for a detailed reliability assessment of this type of connection is described in this article. The resulting behaviour of the numerical model based on the tensile test of the basic material and suitable boundary conditions was validated by a physical experiment. The computational procedures presented in the article will facilitate the design of steel structures in the field of global static analysis of TWCF light steel structures because the described methods can be generalised and applied in commonly available commercial software. Two variants of the model were prepared and evaluated—with and without slippage in the press jaws. Comparison of the numerical model and experimental results shows compliance.

“…For atypical nodes for which there are no standard calculation procedures, tests are carried out in the laboratory, comparing the results obtained in FEM-based programs (comp. [6,7]) and analytical calculations to complement the standard dimensioning algorithms. The analysis of bolted connections was carried out by many researchers [8][9][10][11][12], these tests took place under various conditions, e.g.…”

The paper presents a solution that includes strengthening the connection of a support column with beams from both sides, placed in a vertical plane together with the pole. All the bar elements connected in the analyzed node were made of hot-rolled steel I-sections. Due to the need to increase the load on the joined beams to the pole, load-bearing capacity of the primary connection is lost, which necessitates the reinforcement of the existing connection. The analysis carried out in this paper shown exceeding the allowable stresses in the column web at the place of joining the beams. The calculations made in this paper showed the possibilities of restoring the safe operation of the connection node in question, by introducing elements increasing its load-bearing capacity. In addition to analytical calculations, numerical analysis was also performed using the ADINA program.
