“…The analyses presented in the study show that it is useful to verify the information contained in the manufacturer's documents. The FEM method can be employed in the analysis of thin-wall profiles to verify calculations [10] and assumptions of the study for the adopted model [11,12].…”

“…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 final design, however, often lacks an advanced numerical model with an exact static analysis of structures' behaviour [15,16]. Existing publications have analysed problems of numerical modelling of structures based on thin-walled sections [17,18], steel bearing elements [19], or reinforced concrete structures [20], while the problem of the modelling of the clinch connection has not yet been thoroughly explored. The results of the tests can lead to the calibration and validation of the mathematical models [8,21,22], which should ensure the conformity of the numerical model and the actual behaviour of the studied structures [23].…”

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.

“…It is especially important to ensure that the designed joints do not introduce local instability into the structure and are sufficiently rigid and load-bearing. A typical example of the benefits of TW-CRCS are roof purlins (see Figure 1) [1,12,13]. The combination of welded steel frame and longitudinal TW-CRCS is used mainly for large spans [14].…”

Physical Tests of Alternative Connections of Different High Roof Purlins Regarding Upward Loading

Thin-walled cold-rolled sections are used in the construction industry, especially in the roofing of large-span halls. The load-bearing capacity of a thin-walled structure depends to a large extent on the load-bearing capacity of the details at the point of attachment to the structure and the interconnection of the individual thin-walled elements. Therefore, in the case of thin-walled structures, it is necessary to use additional structural elements such as local reinforcement, stabilising elements, supports, and other structural measures such as the doubling of profiles. This paper focused on the behaviour of tall Z300 and Z350 mm thin-walled trusses at the connection to the superstructure regarding upward loading (e.g., wind suction and so on). Two section thicknesses, 1.89 mm and 2.85 mm, were experimentally analysed. Furthermore, two types of connections were prepared, more precisely without and with a reinforced buckle. The experiments aimed to investigate the behaviour and load-carrying capacity of the detail of the roof truss connections to the supporting structure. The resulting load capacity values were compared with normative approaches. Analyses of the details of the bolt in the connection are also presented. The paper presents a practical evaluation of the physical test on real structural members.
