Abstract
The presented research aims to investigate how the choice of steel grade affects the resistance of T-shaped RHS-to-RHS structural connections, specifically those involving an offset of a brace toward the wall of a chord. To assess the mechanical resistance of these connections, the numerical non-linear FE modelling with ABAQUS software were utilized, which is then validated against results obtained from the analytical model developed by Kalmykova & Wald [1]. Material modelling is carried out for steel grades S355, S460, and S690, using standardized parametric curves as outlined in EN 1993-1-8. It is evident that variations in material properties and the fy/fu ratio influence the behavior of these connections, particularly at the 3% deformation level.
