“…Through this approach, calibration was achieved using a finite element mesh with an approximate size of 3 mm, comprising 3 elements along the plate thickness. The C3D8 element type [2] was employed, and a friction coefficient of 0.25 was defined for the tangential interaction [10].…”

“…In the former arrangement, the adjacent plates prevent the critical one from the curling effects. Conversely, in the latter configuration, the outer plates are susceptible to the curling effect, depending on the employed geometric parameters [10].

The use of stainless steel in structures has been improved; nevertheless, the application of this material is not considered trivial by most designers, as there as still limited design codes providing specific rules. Current codes provide conservative approaches in certain cases, which do not corroborate with the objective of reducing the initial cost of projects incorporating stainless steel. In order to contribute to an adequate comprehension about the structural behavior of austenitic steel in bolted connections, a study was conducted regarding the influence of geometric parameters on the connections with a bolt under two shear planes, encompassing the evaluation of the phenomenon recognized as curling. Concerning to conclusions, it was observed that the geometric parameters e1, e2, d0, affects the curling effects, which has the potential to compromise the structural behavior of a thin‐plate connection if this deformation is greater than the thickness of the plate. Furthermore, the results provided by the equations employed in the design codes was assessed in this study, revealing an adequate prediction of the SCI in terms of the failure mode. However, both the manual and current codes exhibited conservative load for the investigated connections.

In this paper, the design of austenitic stainless steel channel sections subjected to minor axis bending, specifically with tension in the web (“u” orientation) is analyzed. The values of moment resistance are predicted using Eurocode 3 criteria and the Continuous Strength Method (CSM), which are then compared with numerical models to assess effectiveness. The modeling is performed through ANSYS and calibrated with literature tests. It was found that Eurocode presents a considerable disparity in results, as well as an overly cautious response (on average, half the numerical load). The CSM reflects the performance more accurately but still with a certain level of conservatism (on average, around 35% lower).
